Acer Aspire S7 vs Lenovo IdeaPad Yoga 13 vs Asus Taichi 21:Who is the best?

Acer Aspire S7                                                                                                                                           The Acer Aspire S7 is a premium-looking ultrabook, with great performance, strong battery life, and a high-res touch screen.

But, The expensive S7 is priced well beyond most other touch-screen Windows 8 laptops. The touch pad is not as responsive as it should be.

The bottom line: One of the few standout products from the first wave of Windows 8 laptops, the Acer Aspire S7 proves that Apple does not have a monopoly on great design.                                                     Specifications

But, Tablet mode leaves the keyboard exposed, and the Yoga 13 costs more than standard ultrabooks with similar components.

The bottom line: The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience.                                                                Specifications

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
