Lenovo IdeaPad Yoga 11S vs Acer Aspire P3 vs HP Envy x2 :Who is the best?

                                                                                                                                                                                                                                                                                                                                             Lenovo IdeaPad Yoga 11S                                                                                                                                                                           Functional and flexible, the Lenovo Yoga 11S looks to be just what we want in an ultrabook. Light enough to travel easily, and so small it can tuck in any bag with ease.The Lenovo IdeaPad Yoga 11S is a great 11-inch ultraportable touch-screen laptop that also has a flip-around display for tablet and hybrid use.
But, Recent 11-inch laptops from Apple and Sony have raised the bar for ultraportables, especially when it comes to battery life. The Yoga 11S needs an upgrade to Intel's latest processors.
The bottom line: Like the larger 13-inch model, the 11-inch Lenovo IdeaPad Yoga 11S is a useful hybrid that doesn't forget it's a laptop first, but it's stuck with what feels like old hardware for now.                                                                                              Specifications

All the hardware and clever stuff can be found in the 19.75 mm thin slate itself.The Acer Aspire P3 is a solidly built, full Core i5 Windows 8 tablet with its own keyboard for under $1,000. The lower-res display at least looks crisp.
But, Generic design, a cheap-feeling keyboard case, last-gen Intel processors.
The bottom line: Yet another Windows 8 Core i5 tablet, the Acer Aspire P3 has only one thing in its favor: it costs a maximum of $899.                                                                                                                                                                                   Specifications

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.
