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.

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.

Optical DriveNone Price;$749.99 to $899.99 VS Microsoft Surface Pro Making your mind up about the Surface Pro is less about what it is and what it does and more about what you want out of a tablet. As a hybrid PC it's an undeniable compromise - but that's no bad thing.The Microsoft Surface Pro fits a full ultrabook experience in a compact 10-inch tablet. Thanks to the ingenious Type and Touch covers, it offers a comfortable interface and typing experience. The clean, crisp design and sharp 1080p screen rise above the competition.
But, The battery life is disappointing, and more ports would be nice. The 64GB model barely has any free storage. It costs as much as a regular laptop, especially because the cool keyboard cover isn't included by default.
The bottom line: The Surface Pro's gutsy design successfully reinvents the Windows 8 laptop by cramming an ultrabook experience into the body of a 10-inch tablet. Those wanting to go all-in on the tablet experience won't regret buying the Surface Pro, but we're holding out for a future, more polished generation of the device.
