Microsoft Surface Pro 2 The Surface Pro 2's display may not have received an upgrade, but then it didn't need one. It's still a fine IPS panel that helps bring Windows 8.1's colorful and vibrant nature to life. The tablet itself is easier to use thanks to improved keyboard covers - even the Touch Cover 2 will prove more than adequate for most this time around.The Microsoft Surface Pro 2 is a faster, longer-battery-life version of the original model, upgraded with a current-gen Haswell processor. The keyboard cover is also improved with backlit keys, and is among the best tablet accessories ever devised.The Surface Pro 2 is a very tough product to judge, which is what makes it interesting. The good news is Microsoft has sorted out the most serious issue with the first version: the battery life. At around eight hours, the Surface Pro 2 mixes it with the Ultrabooks like the Samsung Ativ Book 9 Plus and Sony VAIO Pro 13, even if it still falls a little short of 'tablet class' battery life.
But, The Surface Pro 2 remains stubbornly thick and heavy compared with some sleeker competitors. The base 64GB version may leave you starved for storage, and the keyboard cover, practically required, should be included instead of sold separately.
The bottom line: Microsoft's subtly updated Windows 8.1 tablet feels more like Surface Pro 1.5 -- improved battery life and better accessories make it a worthwhile (albeit pricey) laptop replacement, but it's still not an iPad-level category killer. Specifications

Weight2 lbs Price $899 VS Lenovo ThinkPad Twist The ThinkPad Twist has great Lenovo construction, a responsive touch screen, and a center hinge for flipping into tablet mode, all for a very reasonable price.The Twist has an uncommon size 12.5-inch screen, and at 1.6 kg is heavy for an Ultrabook of this size, let alone a tablet that usually weighs much less than half that.The ThinkPad Twist has a third-generation Intel Core i5-3317U processor, 4GB of RAM (3.82GB usable), and a 500GB HDD spinning at 7200rpm alongside a 24GB SSD caching drive. The Twist also has built-in Wi-Fi 802.11a/b/g/n, Bluetooth 4.0, and a slot for a SIM card, for users who want to be connected But, The screen accelerometer can have a mind of its own, flipping into portrait view randomly. Battery life is merely OK, and the screen resolution is low for a modern laptop/tablet convertible. The bottom line: Slightly less conservative-feeling than the average ThinkPad, the well-made ThinkPad Twist offers one of the better tablet modes from the first wave of Windows 8 convertibles.

At 10.1-inches and weighing less than two pounds, it fits easily in a bag or large purse, and you'll likely forget you're even carrying it. Battery life is excellent.
But, In laptop mode, the system is awkwardly top-heavy, and the puny keyboard and touch pad are not designed for serious use.
The bottom line: Offering low-powered Intel Atom tablet/laptop hybrids for $750 or more is a dodgy proposition for budget-looking systems such as the Iconia W510, but all-day battery life is a great selling point.
