Seagate announced today the shipment of its 4TB Desktop HDD 3.5-inch internal hard drive for general consumers. While this is not the first 4TB hard drive on the market, the company says it's the first that uses the 1TB-per-platter design. Basically, on the inside, the Desktop HDD comes with four platters (disks), each offering 1TB of storage space.

The Desktop HDD is also the first desktop internal drive from Seagate that uses the new streamlined naming convention. Seagate's consumer-grade hard drives were formerly called Barracuda. Earlier this year, the company also shipped the first hybrid drive of the same naming scheme, the Laptop Thin SSHD.

The new Desktop HDD comes with 64MB of cache memory and supports the latest SATA 3 (6Gbps) standard. It also works with previous versions of SATA, including SATA 2 (3Gbps) and SATA (1.5Gbps). Unlike the previous Barracuda drives that spun at 7,200rpm, the new Desktop HDD spins at only 5,900rpm and consumes about 35 percent less energy. Seagate says that the drive will still offer fast performance with the sustained writing speed of about 145MBps.

According to Seagate, the new drive is designed for both desktop computers and external storage solutions, such as NAS servers or external hard drives. Generally, hard drives of 2TB or larger require a modern operating system (Windows 7 or later) and UEFI BIOS to work, but the Desktop HDD comes with DiskWizard software that allows it to work with Windows XP. To use it as a boot drive, however, UEFI BIOS is needed.

To put things in perspective, 4TB is equivalent to about 500 hours of HD video, 1 million MP3 songs, or 800,000 digital photos. The 4TB Desktop HDD is about 800,000 times larger in capacity than the first desktop hard drive Seagate introduced back in 1979, but the physical size has remained about the same.

The 4TB Desktop HDD is available now and costs about $190, which is much lower than its competitors.

General Things About Samsung Galaxy S4

Our Samsung Galaxy S4 release date, price and specs article will be updated regularly with the latest information as we have it, so check back often

It's official and it's now here, the Samsung Galaxy S4 has been revealed in New York. Although many of the features had been leaked in the weeks leading up to the event, the launch was still a time for Samsung to show-off its latest handset, while no doubt making sure that Apple's got its work cut-out with the iPhone 5S.

Here we'll take a look at the phone's new features and outline its key specifications, as well as rounding up the current UK prices. For a more in-depth look, check out our Samsung Galaxy Specs article.

SAMSUNG GALAXY S4 DESIGN

With the Galaxy S3 proving to be such a success, Samsung hasn't strayed too far from that design with the Galaxy S4. The rounded edges and lozenge-shaped home button at the bottom of the phone are all instantly recognisable.

The Samsung Galaxy S4 is thinner and lighter than the Samsung Galaxy S3

While the S3 looked and felt, well, quite plasticy, the Samsung S4 looks that much nicer and more like the high-end phone that it should be. It has a polycarbonate case, but it's now slimmer (7.9mm) and lighter (130g) than its predecessor.

Two versions of the phone will be available: Black Mist and White Frost. It's hard to pass judgement on the phone until we've seen it in the flesh, but in the shots we've seen it certainly looks like a step up from the Samsung Galaxy S3.

Available in black or white, the Samsung Galaxy S4 is instantly recognisable

SAMSUNG GALAXY S4 SCREEN

As expected, the Galaxy S4 has a 5in Full HD (1,920x1,080) Super AMOLED screen. That's a stunning 441ppi, making this one of the highest-density phones that we've seen. The HTC One manages slightly more at 468ppi, thanks to its slightly-smaller 4.7in Full HD screen. On balance, though, you're going to find it hard to tell the difference or spot individual pixels on either screen.

There was no mention of the Green PHOLED technology, which was rumoured to be making its first appearance here. However, we've been impressed with Samsung's Super AMOLED technology before and it's always been power efficient, helping to save battery life.

As expected, the screen can be operated just by hovering your finger over it, giving rise to two new features. Air View lets you hover over content, such as an email or photo, to preview it without having to open it. Air Gesture, lets you change tracks, scroll through a web page or answer a call with the wave of your hand. We haven't had chance to try the system out yet, but this should make fine-control of the touchscreen operating system that little bit easier.

Air View and Air Gesture let you operate the touchscreen without touching it

Gorilla Glass 3 helps make the phone durable, although we'd still recommend a screen protector or case if you're going to keep your phone in a pocket with sharp items, such as keys.

SAMSUNG GALAXY S4 CAMERAS

Cameras are an important part of any smartphone, with many people preferring them to compact cameras. From the specifications, Samsung hasn't let us down with the Galaxy S4 camera, with a 13-megapixel rear camera, complete with Flash and a high-speed shutter mode. At the front is a 2-megapixel camera.

The 13-megapixel rear camera certainly has impressive specifications, but the front camera can be used to control the phone

Now, two cameras on a smartphone is hardly something new, but with Dual Camera you can operate both of them at the same time. It feels a little gimmicky to us, but the idea is that you can film yourself with the front camera and then superimpose yourself on the footage from the rear camera. The examples we've seen look a little twee and we're not sure that most people want their faces to appear surrounded by a postage stamp border over the footage they're recording.

You can superimpose yourself as a floating stamp in videos, if you like that kind of thing

The front camera also serves a purpose in controlling the phone with Smart Pause. This technology knows when you're looking at the screen so it can, for example, pause a video when you turn your head and look away. As soon as you look back, the video continues. It's a neat way of using the cameras for more than just still images and video.

SAMSUNG GALAXY S4 PROCESSOR

We were expecting the Octa-Core Samsung Exynos 5 processor in the phone and that's an option, with a 1.6GHz model. However, a 1.9GHz Quad-Core version of the phone will also be sold, depending on where you live in the world. Samsung hasn't specified yet which version we'll get in the UK, although we would expect to get the Octa-Core model.

The company tweeted a rendering of the new chip, which is also rumoured to power the new Galaxy Note 3 phone/tablet, from its @SamsungExynos Twitter account, so whetting the appetites of Samsung fans everywhere.

The new chip's eight-core design is based on ARM's big.LITTLE architecture. This means that there are four powerful Cortex-A15 cores for the phone's most power-hungry functions, and four lower-power Cortex-A7 models to take care of simpler tasks. When the phone isn't needed to do anything fancy, the more powerful cores shut down, extending battery life.

SAMSUNG GALAXY S4 BATTERY

Speaking of battery life, the new handset will use a 2,600mAh battery. That's 500mAh bigger than the one in the S3 and should be big enough to cope with the slightly-enlarged screen, and the greater demands of 4G, while still running all day.

The battery is also removable, so you can carry a charged spare if you're going to be out for a long time. It also means that a failing battery can easily be replaced.

SAMSUNG GALAXY S4 4G AND WIRELESS

You can't make a modern phone and not support the latest wireless standards, so the Samsung Galaxy S4 has full support for 4G LTE networks. Global 4G support has been promised, supporting download speeds of 100Mbit/s and uploads of 50Mbit/s. Full 3G and 2.5G support is, of course, also present.

For use at home there's also better Wi-Fi support, with the new 802.11ac standard supported. We've seen this networking standard deliver speeds well over 200Mbit/s, so using super-fast broadband speeds on your phone at home is going to easy.

SAMSUNG GALAXY S4 NFC

NFC makes an appearance, so the phone will be compatible with Google Wallet, so you can pay for goods in compatible shops using just your phone. It will also support Visa's payWave, widening the choice and range of places that you can shop in.

In addition, Samsung showed some other ways that NFC can be used. One of the most different was Group Play. By tapping your Samsung Galaxy S4 to another one, you can share music and pictures. Samsung has also promised that the technology will support multi-player gaming and it's opening up the SDK to encourage other companies to develop for it.

SAMSUNG GALAXY S4 STORAGE

No great surprises on the storage front, with 16GB, 32GB and 64GB models announced. However, it's good to see that there's still a microSD card slot, so you can add up to 64GB of storage. Depending on the prices, it may even work out cheaper to buy a lower-capacity model and then upgrade it when you need to with a memory card.

SAMSUNG GALAXY S4 S HEALTH

With fitness accessories apps being big business, Samsung clearly doesn't want to miss out and has launched S Health with the Galaxy S4. Using your phone a variety of accessories, you'll be able to measure your weight and health.

SAMSUNG GALAXY S4 OTHER FEATURES

If all of that wasn't enough, the Galaxy S4 also has an IR transmitter, which you can use to control your home entertainment kit via the WatchOn app. There's also S Voice Drive, which puts up a simpler interface for when you're driving and recognises voice prompts. Finally, when you're abroad the translation services let you type in a message and have the phone read it out in a different language; the spoken reply is then converted back into your language on the screen.

SAMSUNG GALAXY S4 RELEASE DATE

Samsung has promised to have the phone out by the end of April. Exact launch dates will depend on the country, but we expect the UK to be one of the first on the list. We'll bring you updated information as and when it becomes available.

SAMSUNG GALAXY S4 PRICE AND UK NETWORKS

The good news is that you won't be short of choice when it comes to buying the Samsung Galaxy S4. Two of the major UK networks have confirmed that they will be carrying the new phone - no great surprise, when you consider the huge success of the Galaxy S3 and the amount of hype that has been building up to the launch of the S4.

As you'd hope considering the Galaxy S4's LTE capability, it will be available on the UK's only 4G network - EE - and Three has also thrown its hat into the ring.

Vodafone and O2 have yet to say either way, but we find it hard to believe that they will pass up the chance to stock this year's potential biggest seller.

Pricing hasn't yet been announced, but we can take a fair stab at expected prices. We'd imagine that launch prices will be the same as for the S3 when it launched back in May - a wallet-busting £499. Once again though the tough competition from Google's own Nexus 4 device may force Samsung to lower its price in order to compete - unless of course the hardware specification is a big step forward.

On contract you're likely to be looking at £30-40 a month minimum, and considerably more with a 4G service such as EE. This will be an expensive handset, though probably still a little less than the iPhone 5 costs.

• Waterproof and dust-resistant

• Powerful quad-core processor

• MicroSD card slot

• Excellent camera

Bad:

• Fingerprint magnet

• No Android 4.2 out of the box

In this review,We cover about

1. Should I buy the Sony Xperia Z?

2. Design and display

3. Processing power and software

4. NFC and connectivity

5. Camera and video recording

6. Battery life and storage

7. Conclusion

Specs:

The Sony Xperia Z is the latest entry in the Japanese company’s burgeoning range of Android smart phones and comes with the kind of specifications that dedicated mobile geeks stay up all night dreaming of. There’s a 1.5GHz quad-core processor, 2GB of RAM, a 13.1-megapixel camera, 4G cellular connectivityand 16GB of built-in storage, which can be augmented using microSD cards.

All of that lovely cutting-edge tech is protected by case design which will survive a dip in water of a depth of up to 1 metre for thirty minutes. And it's dustproof as well.

The Sony Xperia Z is available on a monthly contract with prices starting at around £26. If you’d rather pick one up SIM-free then you’re looking at handing over a good £450.

If you’re keen to take advantage of the phone’s 4G power, bear in mind that the only network provider in the UK to support the service currently is EE, and it’s yet not known if it’ll be offering the Xperia Z on a monthly contract.

1. Should I buy the Sony Xperia Z?

The Xperia Z is the first big Android phone launch of 2013, and marks Sony’s entry into the rapidly-expanding quad-core battlefield. It’s also something of a monster, thanks to its gigantic 5-inch 1080p “Reality” display. If you balked at the size of the HTC One X and Samsung Galaxy S3, then the dimensions of this blower are likely to cause your hands considerable pain.

Assuming you don’t have the little paws of bear cub, there’s an awful lot to like here. The 1.5GHz quad-core Snapdragon CPU is blisteringly fast, and features such as HDMI-out and NFC support ensure that the Xperia Z is at the cutting-edge of mobile technology. The lack of Android 4.2 is somewhat disappointing, but Sony is keen to stress that the phone will be upgraded this latest version shortly after release, so it’s not as big an issue as you might imagine.

With the Samsung Galaxy S4 on the horizon, Sony is making a very bold move by launching this phone now, but unless the S4 is capable of making your morning coffee and taking the dog for a walk then I doubt the Xperia Z is going to be totally outclassed. If you’re in the market for a new phone right now and are comfortable with a screen size that's almost tablet-like in its proportions, then this is a recommended purchase -- although it’s worth considering the Nexus 4, which is available SIM-free for around £200 less.

2. Design and Display

The Xperia Z marks a drastic departure for Sony’s designers -- gone are the curved edges and rounded corners which defined the likes of the Xperia T and Xperia Arc S. Instead, we’ve been gifted a slab of tech which looks eerily like the monolith in 2001: A Space Odyssey (if you’ve got the black version, at least).

It’s a massive stylistic change for Sony, but one I can fully get behind. The Xperia Z looks imposing and beautiful at the same time, and is sure to get the pulses racing of gadget fiends and casual users alike.

In a move which imitates the iPhone 4S and Nexus 4, the Xperia Z is clad in shatterproof glass front and back, giving it a glossy appearance which makes it look seriously snazzy -- but it also means it attracts fingerprints like nobody’s business. At just 7.9mm in thickness, it’s also extremely svelte. Weighing in at 146g, it’s not the lightest phone on the market, but it’s unlikely to strain your trouser pocket either. Around the edges of the phone you’ll discover additional strips of glossy plastic, which further enhance this handsome aesthetic.

At just 7.9mm thickness, the Xperia Z is almost as thin as the iPhone 5

You’ll also find yourself inspecting each corner for ports and openings -- which are all covered by flaps in order to facilitate the Xperia Z’s ability to withstand dust and water ingress. The phone will happily take a swim at depths up to 1m, for thirty minutes at a time, which essentially means if you drop it down the loo but retrieve it swiftly, there will be no harm done -- aside from the indignity of having to shove your hand down a filthy toilet, of course.

All of the phone’s ports are covered by panels to ensure it maintains its waterproof prowess

The Xperia Z’s 5-inch 1,920x1,080-pixel 'Reality Display' pops with colour and vibrancy, and packs a pixel density of 443ppi -- leaving theiPhone 5's 326ppi panel eating dust. If rumours are to be believed, it should also be impressive enough to go toe-to-toe with the Galaxy S4’s display.

The Xperia Z’s 1080p screen is just beautiful, offering incredible clarity and definition.

This 1080p screen has the kind of clarity you’d normally expect from your television. It’s impossible to discern individual pixels, and high-res images look stunning. Sadly though, some of the app icons on Android haven’t been designed with that kind of resolution in mind, and end up looking a bit blurry and ill-defined. This complaint can hardly be levelled at Sony though. Apart from a very slight issue with viewing angles, the Xperia Z’s screen is a winner.

3. Processing power and software

It’s taken Sony a while to get there, but the company has finally joined the quad-core club with this flagship phone. Inside that skinny case beats a 1.5GHz quad-core Snapdragon S4 Pro chip, backed by a roomy 2GB of RAM. This makes it one of the fastest Android phones around, and the usual gamut of benchmark tests reveal some truly fearsome power. Antutu Benchmark gives the phone a score of 20,031, pulverising the Samsung Galaxy S3’s 12,467, while Quadrant Standard awards the phone a 7,995, which trumps the HTC One X’s rating of 4,904.

In GLBenchmark 2.5.1’s Egypt HD on-screen test, the Xperia Z clocks a score of 3,399 at 30 frames per second, and Vellamo -- which tests web performance -- rates the phone at 2,185, beating both the Galaxy S3 (1,580) and the HTC One X (1,625).

Finally, there’s the Epic Citadel benchmark, in which the Xperia Z earns a rating of 56.6 frames per second on the high performance test and 55.7 on the high quality test. This is one seriously powerful blower, and no mistake.

The 5-inch screen means a big chassis,
 which could cause problems for those of you with small hands.

All of this raw power means that Sony’s quad-core beast makes short work of most Android applications and games, but surprisingly there are still brief moments of slowdown and stutter. If I was reviewing this phone six months ago then I’d be willing to put this down to Android’s traditional performance issues, but since the Nexus 4 arrived and proved that Google’s OS can run as smooth as silk, I’m less inclined to let it slide. Hopefully a software update can rectify the occasional pauses.

The phone comes with Android 4.1 on board, although Sony is adamant that a 4.2 update will be pushed out soon after launch. Sony’s own skin sits on top of Google’s OS, and offers a series of exclusive embellishments. The lock screen is particularly fetching. It imitates the look of a set of window blinds, and moving your finger over the surface of the screen causes the blinds to ripple and bend. You can also access your music player and camera from the lock screen, although the camera app doesn’t fire up anywhere near as quickly as the one on the Nexus 4.

The Xperia Z’s lockscreen imitates the look of window blinds, reacting realistically to your touches and swipes.

Sony has toned down its custom widgets on this phone, and the pointless Timescape social aggregator has thankfully been removed entirely. The Small Apps system which premiered with the Xperia T has been retained, and allows you to launch things like voice recorders and calculators from the Android multi-tasking menu. More of these apps can be installed from the Google Play market, and although the number available is still quite limited, they’re moving in the right direction.

4. NFC and connectivity

NFC has been part of Android since the Nexus S launched in 2010, but aside from Android Beam and the ability to automate elements of your phone’s functionality with special NFC tags, few hardware manufacturers have been able to fully exploit its power. Thankfully, it would appear that Sony is taking the tech very seriously indeed with the Xperia Z.

NFC allows the device to communicate with other Sony products, such as the latest range of Bravia televisions. Just by touching the phone to the TV, you can mirror the screen to show off your monstrous 13.1-megapixel snaps.

The bundled dock allows you to charge the phone and use it as a music player or night stand.

This kind of connectivity feels like the future, and it’s encouraging to see Sony adopting such a forward-thinking approach. Of course, you’ll have to invest in an expensive telly to take advantage of it, but knowing such a feat is possible could influence your purchasing choice next time you’re in the audiovisual section of your local electronics retailer -- a fact which Sony really should be exploiting with more enthusiasm.

The Xperia Z comes with support for 4G connectivity, which means its ready for the future of mobile. Sadly, only one network in the UK is offering this speedy service, so unless you’re already using EE and don’t mind buying the phone SIM-free, you’re not going to be able to take advantage of those blistering data transfer speeds just yet. This of course could change as 2013 rolls onwards -- expect to see other providers offering 4G in the not-too-distant future.

5. Camera and video recording

Sony’s no stranger to putting silly megapixel counts on its mobile phone cameras and the Xperia Z is no exception -- it offers an incredible 13.1 megapixels of imaging goodness. All the pixels in the world don’t mean a jot if the actual camera is a duffer, but mercifully that isn’t the case here. Sony’s latest phone produces some wonderful images, providing lush shots regardless of lighting conditions.

The camera on this blower is noth to be sniffed at (click image to enlarge).

The usual selection of options are present and correct, including image stabilisation and HDR. You can also use 'Superior Auto' and allow the phone itself to select the correct scene for the snap you’re taking. HDR is also available during video recording, which results in some gorgeous footage -- although like HDR stills, you should be prepared for some almost unreal, otherworldly results.

6. Battery life and storage

With a bright 5-inch screen and quad-core CPU it’s understandable that the Xperia Z is quite a hog when it comes to battery life. If you’re using the phone a lot and the screen is on a high brightness level, you’ll only get around four to five hours.

Sony is clearly aware of this and has introduced Stamina Mode, which completely disables all mobile data activity when your screen powers down. When engaged at night, Stamina Mode is aggressive enough to ensure that battery consumption is as meagre as possible -- during our test, we noticed that the battery level hardly dropped at all during the wee hours.

Like the Nexus 4, the Xperia Z has a glossy back panel which attracts fingerprints

Of course, losing all connection to the outside world isn’t going to make the Xperia Z particularly useful in the daytime, which is why Sony has also factored in customisation options. You can add exceptions to Stamina Mode to allow certain apps to maintain a mobile data connection when it is engaged. While it’s true that the same level of power management can be achieved with apps such as Tasker andLocale, it’s encouraging to see Sony take such a proactive approach.

7.Conclusion

Sony’s previous Xperia devices have always been a little lacking in some way, but with the Xperia Z, it feels like it's finally found its stride. Aside from the lack of Android 4.2 -- which won’t be an issue for very long, according to Sony -- this blower is packed full of good stuff.

The quad-core processor is a monster, the 1080p screen is pin-sharp and the waterproof design will help the phone find favour with butter-fingered mobile users who are prone to accidentally dropping their expensive devices into random pools of liquid.

With the Xperia Z, Sony has fired the first shot in the smart phone war of 2013, and while we’re sure that Samsung’s reply -- which should come in the shape of the hugely-anticipated Galaxy S4 -- will be equally impressive, this is one of the best Android devices money can buy right now.

First Image Of The Samsung Galaxy S4

It was published online in the first image of the Samsung Galaxy S4  which is the new smartphone with Android heart of the next generation to which the South Korean manufacturer should remove the veil in the coming months.We have  got the picture from reliable sources, that have expressed close to Samsung.

The design of the alleged Galaxy S IV bears a striking resemblance to that of the Galaxy S III but unlike the latter the display takes up a larger share of the device: the edges appear to be even more reduced and it is not even present physical Home button that has so far characterized the series. The above is replaced by a digital button, as now happens in many tablet.

The panel seems to be slightly increased compared to the current generation of smartphones. According to rumors it will be of 4.99-inch Super AMOLED with Full HD resolution , 1920 × 1080 pixels.The rest of the hardware specifications as we speak of the presence of a CPU Quad-core Exynos 5450 2.0 GHz, a GPU Mali T658, 2 GB of RAM and a kit of two integrated cameras, a rear with 13 megapixel camera and a 2 megapixel front which would ensure a good quality video .The operating system should be Android 4.2.1 Jelly Bean.

Picture of the alleged leaked Samsung Galaxy S4:

Clearly Samsung has not yet confirmed the development of the Samsung Galaxy S4 and before the official presentation of the device so all the leaked information are to be taken with a grain of salt. However, the leaked image looks pretty real and it is possible that the new smartphone is right in this photo.

Dell XPS 12 Ultrabook Review

Introduction & Specification:
 
Tablets are extremely popular right now, but many users still need a more powerful machine to do serious work. For people who don't want two devices but desire the touch screen controls and convenience of a tablet, as well as the productivity capabilities of a notebook in a single machine, a convertible ultrabook may be a good fit.
 

 
We're starting to see more and more ultrabooks that convert from a traditional laptop into a tablet. Not long ago, we took a closer look at Lenovo's IdeaPad Yoga 13 Ultrabook which features a touchscreen display with a dual-articulating hinge that allows the machine to convert to tablet mode. Today, we're going to take a hands-on look at Dell's XPS 12 convertible ultrabook, which takes a different approach.
 
Dell's XPS 12 features a display that's surrounded by a thin silver bezel. As you can see from the photos, the display rotates on a hinge located in the middle of this bezel. The machine runs on Windows 8 and takes full advantage of the operating system's touch capabilities with its touch display.
Dell offers various configuration options with the XPS 12. We're testing one of the lower-end models with a Core i5 CPU, 4GB of RAM, and 128GB solid state drive. Other configurations feature up to a Core i7-3517U processor, 8GB of RAM, and a 256GB solid state hard drive.

Design And User Experience:
 
The XPS 12 features machined aluminum edges, Corning Gorilla Glass, and a carbon fiber base and lid to give it durability. Rotating the display in and out of tablet mode is smooth, and the machine has a slight catch to lock the display in place in both configurations. When locked in place, the screen is perfectly flush with the aluminum edges. While rotating the display, you'll notice the frame that surrounds the display is nice and solid.
 

 
We found the XPS 12's display to be colorful and vibrant. The 12.5-inch screen supports a 170-degree viewing angle and has an HD resolution of 1920 x 1080. This 400-nit display is brighter than the typical 200-nit panels, making the XPS 12's screen easier to see in brightly lit environments and outdoors too.
 
The XPS 12 has a full size, chiclet keyboard that's spill resistant. This keyboard is also backlit which is a nice extra if you're frequently working at night or in low-light conditions.  The XPS 12 also has a glass integrated touchpad with gesture support. This touchpad is nice and roomy. On some occasions, we accidentally hit the touchpad while typing, thereby moving the mouse. This is annoying but if you don't rest your hands while typing, it shouldn't be a problem. The touchpad is flush with the body of the XPS 12.
 
One of the advantages of the convertible design used by Dell is the fact that the keyboard is hidden when the XPS 12 is in tablet mode. This design prevents you from accidentally hitting keys in tablet mode, protects the keyboard from accidents, and also gives you a smooth surface to grip when holding the machine.
 
 
 
 

 

 
On the left edge of the XPS 12, you'll find a screen-rotation lock button, headphone/microphone combo port, power switch, and volume controls. Instead of a traditional button that you'd push for power, the XPS 12 uses a sliding switch. The right edge of the machine houses five battery status indicator lights, battery status button, USB 3.0 port with PowerShare, another USB 3.0 port, Mini-DisplayPort, and power adapter port.
 
Above the display, you'll find two digital array microphones, a camera status light, the camera, and an ambient light sensor located near the center of the machine. Centered below the display is a Windows button.
In an effort to keep the XPS 12 thin and light, Dell was forced to make a few sacrifices. Like most other ultrabooks, the XPS 12 does not have an optical drive. It also lacks an HDMI port and a LAN port.
 
 
 

 
 
 
 
 
You won't find a lot of icons and clutter on the default Start screen of Dell's XPS 12. Of course, you can still customize this Start screen to your liking. The default desktop is also free from clutter. That's not to say the XPS 12 doesn't come with a few preinstalled apps, however. Out of the box, you'll find various Dell tools preinstalled including Getting Started, Digital Delivery, Dell Shop, Backup and Recovery, PC Checkup, and others. A trial version of Microsoft Office is also preinstalled on the system.
Dell's Support Center is powered by PC Doctor. This app provides information about the specifications of your exact machine as well as providing various checkup and backup services. The app notified us of BIOS updates, Windows updates, and offered to improve the boot up time of the machine.
 

 
 
When using the XPS 12 in tablet mode, the screen will automatically rotate according to orientation. The accelerometer isn't quite as fast to respond as some smartphones, but it still adjusts reasonably quickly.
 
Conclusion:
 
As user continue to contemplate the choice between the power and functionality of a full laptop and the portability and touch capabilities of a tablet, we're likely to see more convertible ultrabooks come to market. Dell's implementation of a convertible ultrabook in the form of the XPS 12 is a great one. We like the fact that the keyboard is hidden behind the screen when using the machine in tablet mode. We also appreciate the backlit keyboard on the XPS 12 when using it in laptop mode.
 
 

 
Overall, the XPS 12 performed well in our benchmark tests. It earned the top spot in the PCMark benchmark which measures a system's overall performance and responsiveness. In real-world usage, the system performed well and felt very quick overall. Battery life is a bit of a disappointment with the XPS 12, however. Since the battery is not user replaceable, don’t expect to get a full day's worth of work from the machine without a nearby power source.
 
Dell offers the XPS 12 at a starting price of $1,199.99. More powerful systems than the one we tested, such as models with a Core i7-3517U processor, 8GB of RAM, and a 256GB solid state hard drive are also available.
 
If you're in the market for an ultrabook, you'll quickly discover the XPS 12 isn't the cheapest option out there. However, the XPS 12 is a solid, well-built system that has some additional features you won't find on these lower-priced ultrabooks. For anyone who is willing to spend the premium to get a convertible ultrabook, we encourage you to check out the XPS 12.

Roboy, the Most Advanced Humanoid Robot in the World

Robotics continues to make great strides and with it the hope from man to build mechanical copies of itself. The latest comes from Switzerland, notably from the University of Zurich at the AI Lab was in fact built Roboy , one of the world's most advanced humanoid robot. Roboy finally see the light since the early months of 2013, with a presentation during the event "Robots on Tour" to illustrate the quality of the project coordinated by Professor Rolf Pfeifer.

Humanoid Robot Replicated the Physical Human Aspects

The main feature that stands out from the rest Roboy humanoid robots built to date in the laboratories of universities around the world is its ability to replicate the physical aspects of human beings in a surprising way. every movement is in fact coordinated by artificial versions of tendons, joints , bones and muscles , allowing a flexibility and dexterity in some ways comparable to that of humans. Roboy, in short, wants to be in all respects similar to its creators, copying the physical structure in every aspect.

The size of the robot are currently equal to those of a child of four years, but the team of researchers who are dealing with the IA Lab of development they hope to make further progress in this direction. Meanwhile, the project hopes to raise more funds to continue its evolution, as evidenced by the ability to make a donation in exchange for sponsorship of different parts of the robot during the upcoming performances.

When Humanoid Robot available

Roboy short, once completed will be considered without a doubt one of the most advanced humanoid robot in the world, thanks to the excellent work done in the laboratories of the University of Zurich. His debut could then lead the way for the arrival of new robots in this category, making reality more and more like science-fiction movies that long affect the collective imagination and gives hope for a future where robots and men can collaborate one alongside the other.

The Humanoid Robot is now not a Science-Fiction
