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.
Price;$1,499 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.
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.

Category Ultraportable hybrid Price; $849 VS Asus Taichi 21 The Asus Taichi 21 offers a clever implementation of a dual-screen design in a slim Core i7 chassis.
But, Only one of the screens is touch-enabled, which feels like a major oversight. There are probably only a handful of situations where you'd need an outward-facing display.
The bottom line: More of a clever proof-of-concept than a practical product, the Asus Taichi still delivers on its basic promise, combining two displays for a unique take on the laptop/tablet/hybrid genre. Specifications
