Microsoft Surface RT The Microsoft Surface's Metro interface is innovative, elegant, powerful, and versatile. The tablet feels strong and well-built, runs Office 2013, and includes rich video and music services. Its keyboard cover accessories are the best ways to type on a tablet, period.
Performance: A common misconception is that the traditional desktop isn't available in Windows RT, but that's not true; it's accessed via the desktop tile on the Start screen, but its relevance is severely diminished.
As Windows RT can't run traditional programs you need to use the old style Windows Explorer less, but it's still on hand for browsing file systems, USB sticks, organising folders and more.
The 'charm' bar to the right also includes search and share buttons and these are threaded through every part of the OS, from files to settings, to the information held within apps.Another triumph is the on-screen keyboard, which is large, sensitive and easy to use. It's not as smart as some third-party keyboards on Android, but we typed with two hands quickly and accurately and the extra inch of screen space made it much easier to use than its iOS counterpart.
We had a few problems with the large keyboard panel blocking information we needed, but the icon to show or hide the keyboard is always on hand in the bottom-right corner of the desktop.
As we've already mentioned, performance is a slightly mixed bag. The system is always responsive, with silky smooth transitions and snappy navigation.
However, we found that some apps were slow to load, with lingering splash screens. What's more, 1080p playback was a few frames per second short of perfect.
While we wouldn't say that the Tegra 3 chip performed appallingly, there's certainly no headroom, and it seems to be the graphics core that struggled most.
Multitasking apps never missed a beat, but it was loading the graphically-intensive apps and movies that showed the biggest strain on the processor.
Even some basic games ran at a noticeably low frame rate, so it seems that Windows RT might need some optimisation. Battery life:
Our experience of the battery life has bemused us somewhat. We started off a day with the Surface RT at 100 percent and only used the tablet intensely for around an hour and a half while shooting our video review. We then used the Surface RT in the evening for around 30 minutes web browsing. The next morning, however, the Surface RT needed the mains charger to switch on so the battery had full depleted overnight. Strange considering Microsoft touts 7-15 days idle life. But, The tablet's performance can be sluggish, its Windows Store is a ghost town, Metro takes getting used to, and the Desktop interface feels clunky and useless.
The bottom line: If you're an early adopter willing to forget everything you know about navigating a computer, the Surface tablet could replace your laptop. Everyone else: wait for more apps. Specifications

While the previous entry had some technical issues, the Xperia Tablet Z has the potential to be the company's best tablet yet.The Xperia Tablet Z ships with Android 4.1 (Jelly Bean) and will be upgradable to 4.2.The Xperia Tablet Z is powered by a 1.5GHz quad-core Snapdragon S4 Pro processor and includes 2GB of RAM, supports Wi-Fi, Bluetooth, MHL, NFC, a gyroscope, an accelerometer, and aGPS.The screen is scratch resistant and delivers 1,920x1,200 pixels. Text looked extremely sharp and the colors popped from the screen with a vibrancy seen only on the very best tablets. Price;$499.00 VS Apple iPad 4 The newest iPad's faster A6X processor adds extra system speed and graphics power.It's clear, it's bright, it's crisp; essentially it properly expands the smartphone experience onto a larger tablet and takes us into a new generation of displays. Improved worldwide cellular compatibility makes the LTE model a more appealing proposition. And the iOS App Store remains best in class, with the widest selection.The iPad range remains among the best in class for battery life considering their size and weight, providing a genuine 10hrs use between charges and lasting for weeks in standby.Gaming tends to cause the biggest drain on battery life but you’ll still get 6-7 hours solid play from even the most demanding 3D titles.
But, The fourth-gen iPad is otherwise identical to its recent predecessor -- same size, weight, and Retina screen. It's heavy to hold in one hand, and most older accessories won't work without investing in a pricey Lightning adapter.
The bottom line: The latest iPad adds several tweaks and improvements to secure its position at the top of the tablet heap. It's better all around, but third-gen owners need not apply. Specifications
