HP Envy x2 vs Asus Taichi 21 vs Microsoft Surface Pro :Hot cake is..........................

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.

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

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.
