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 Dell Venue 11 Pro Dell's Venue 11 Pro is one tablet that works in three different ways. You can use it as a typical Windows 8.1 tablet, snap it into a keyboard dock and use it like a laptop, or remotely connect it to a dock hooked up to a monitor or TV to play movies and TV shows on a larger screen.Dell says it has "The power of an Ultrabook, performance of a desktop, portability of a tablet."The Venue 11 Pro is unmatched for practicality. There's a mini-HDMI output; a 3.5mm headset jack; a full-sized USB 3 port; a volume rocker switch; and a Kensington lock slot.The rear panel pops off to allow access to the 32Wh battery, and in a welcome change from its predecessor, the Latitude 10, the Venue 11 Pro charges via micro-USB.The Venue 11 Pro10.8-inch a Full HD (1,920 x 1,080) IPS display and will be offered with Intel's Atom quad-core Bay Trail processors or a fourth-generation Haswell processor up to Core i5 -- supporting up to 8GB RAM, 256GB of storage, WiDi and NFC.With the big screen and quad-core processor you’ll get around eight hours of mixed use from a single charge, and a little more if you turn down the brightness and avoid using Wi-Fi. That’s better than the Surface Pro 2, though not the ARM-powered Surface 2. Eight to nine hours is more than adequate for a day of work, and the Venue 11 Pro has one advantage in that you can remove the back cover and replace the battery with a spare – a real rarity in the tablet world.One thing that sets the Venue 11 Pro apart, however, is that the back cover can flip off, revealing a removable battery. Both versions of the tablet are pen-enabled, and each includes an 8-megapixel back camera. Accessories include a $99 dock that allows you to push the tablet's display to a larger monitor, a keyboard with a back stand, and a full keyboard dock with USB ports.Price:$500.
VS Sony Vaio Duo 11 Sony’s Duo 11 is one of that strange new breed of hybrid Windows 8 devices that can be used as either a tablet or a laptop computer. It's an Intel Core i5 3317U chip clocked at 1.7GHz - the same low power variety found in Ultrabooks. While 1.7GHz may seem low, it can Turbo Boost itself to a whopping 2.7GHz under heavy strain, which means it's no slouch.It’s certainly an attractive looking device, with an excellent high-definition, touchscreen.The Sony Vaio Duo 11 packs an 11.6-inch 1920 x 1080 IPS panel, which looks glorious. Not only is Windows 8's new interface sumptuously represented, but also apps, games and movies too.The Sony Vaio Duo 11 has a fine set of specs for an ultrabook and an excellent full-HD touch screen on which to take advantage of the Windows 8-style interface.Battery life is respectable considering the specifications. We got just over four hours when using Wi-Fi to stream video from iPlayer, so you can probably stretch that to around five hours for lighter web browsing or using simple office software.
But, The Duo's design misses the mark for use as a tablet and a laptop, feeling like too much of a compromise.
The bottom line: While there are certainly things to like about the Sony Vaio Duo 11, the design gets in the way of enjoying them.
