Lenovo ThinkPad Helix The ThinkPad Helix is powered by a third generation Intel Ivy Bridge processor, up to Core i7 and up to 8GB of DDR3 1600MHz RAM. Aiding performance is an SSD of up to 256GB so its performance is top-notch. You’ll be able to choose between Windows 8 and Windows 8 Pro.The Lenovo ThinkPad Helix will be available in an array of spec configurations, but the one we saw demonstrated was a mid-range example, with a Core i5 processor. Core i7 options will also be available. The ThinkPad Helix uses current Ivy Bridge-generation CULV Intel chips, backed-up by 8GB of RAM and a 256GB SSD. The screen and base are each under 2.0 pounds, but that's on the hefty side for an 11.6-inch system. That said, it's 20mm thin, qualifying for ultrabook status, and can run processors up to Intel's current-gen Core i7.Travel-friendly features include 3G/4G antenna options, NFC chip, and a spill-resistant keyboard.The Lenovo ThinkPad Helix feels like a hybrid roadwarrior. It's reasonably light, especially in its class, offers great build quality and careful attention to detail in its construction. It may not be a beauty, but it's one of the better full Windows 8 hybrid designs out there. Performance and battery life
A 1.8 GHz processor and 4GB of RAM may seem small on paper, but in practice the ThinkPad Helix is a surprisingly capable machine. Both the Windows 8 tiled interface and desktop ran smoothly on our review unit.Browsing in either Chrome or Internet Explorer, we could get a dozen tabs going before performance started to chug. This is with the tablet docked in its helpful stand, which provides extra cooling and allows the processor to overclock a little.The performance enhancement is noticeable, and the fans generate minimal noise. This is by no means a gaming machine, but we were able to play some Half Life 2: Episode 2 with an acceptable framerate.The stand also provides additional battery life. With its help, we generally got 7 to 8 hours of web surfing and word processing. As just a tablet, the Helix got between 5 and 6 hours. That's not bad at all, certainly better than a Surface Pro, but one can't help but think of what Haswell could've done for this machine.
Price;$1,499 VS 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 HP Envy x2 The Envy x2 impressed us. Its outstanding industrial design really shows the potential of a tablet/laptop hybrid. The HP Envy x2 has a clean, comfortable design and feels lightweight in tablet form. It has excellent battery life, and works just as well as a laptop as it does as a tablet. Performance: Unfortunately, as soon as we start talking performance we’re confronted by the fact that Clover Trail is still Atom, and Atom is still not in any way, shape or form a performance chip – and that 2GB RAM maximum doesn’t help here either.Don’t get us wrong, for navigating through Windows and average daily use such as browsing the web and running apps or light programs, the Z2760 in the HP Envy x2 runs smooth as butter. Performance is consistently superior to that in the netbooks of yore, especially when it comes to HD video playback and light multi-tasking, and most non 3D-gaming apps you’ll find in the Windows store should run without a hitch.
However, proper multi-tasking; running intensive HD video simultaneously with another program; or using demanding programs like an image editor can still quite easily bring this kind of machine to its knees. In other words, as a tablet the x2 performs admirably, but as a laptop replacement you have to be prepared to put up with its limitations.
3D gaming in anything but the most casual titles, meanwhile, is also a big no-no. Even at minimum settings our test games simply refused to run or crashed after getting through the menus. Mind you, this is not surprising given that Intel’s integrated GMA 3600 chip paired with the Atom Z2760 is derived from an old PowerVR design the benefits of which Windows drivers don’t fully bring out. Hopefully updated drivers will eek out more performance. Battery life: Battery life is impressive, living up to HP’s claim of seven hours when we streamed video from BBC iPlayer. And, of course, there’s a second battery in the keyboard, which provides an additional seven hours of battery life. No ultrabook that weighs a similar amount can claim to last this long. But, The laptop mode is top-heavy, and the awkward tablet detachment mechanism isn’t perfect; it has limited ports; and a slower Atom processor means in performance it's far behind most ultrabooks, even though it’s priced like one. The bottom line: The HP Envy x2’s capacity to be a full Windows 8 tablet or dock with a keyboard works as well as advertised, provided you’re willing to live with slower performance at a high price. You’re paying for style.
