Conclusion: At this point, we're not wildly enthused about any Windows 8 convertible device. The Taichi is one of the best-built of the handful we've seen.
Pros: Two excellent IPS displays, Impressively thin despite extra screen, Solid ultrabook design and performance
Cons: Expensive, Interior screen lacks touch, Gorilla Glass on lid adds weight, Disappointing battery life

Conclusion: There are two kinds of compromises that the Asus Taichi makes: the first is common to even the best of the Windows 8 convertibles we've seen—a computer generally can't be
Pros: Excellent build quality, Both 1080p screens are colorful and have excellent viewing angles, though they're not quite as bright as others we've seen, Great keyboard, Du...
Cons: There's no exceeding 4GB of RAM, which may be an issue for heavy users, Slightly heavier than other Ultrabooks of comparable size, Laptop's screen isn't touch-enabled,...
Excerpt: It’s an exciting, stylish, well-built and thought-provoking Ultrabook Convertible. The ASUS Taichi 21 contains two screens and can be used as a tablet, or a very mobile...
Conclusion: Oh Asus, you tried so hard to impress us with the Taichi 21 – and it worked … at first. The idea behind this hybrid is cool and different, and we want to like it.
Pros: Innovative design and concept, Light for a laptop even with two displays, Full HD resolution on both displays, Outer display is touch and stylus-enabled
Cons: Short battery life, Heavy for a tablet, Uncomfortably high temperatures on the bottom, Few ports, No apps to take advantage of dual-screen design, Performance goes dow...
Conclusion: The Asus Taichi 21 offers a unique dual-display design, but the end result is a good ultrabook combined with a middling tablet, at a fairly high price.
Pros: Dual-display combines laptop and tablet functionality. Gorilla Glass on lid is stylish looking. Quality construction. Intel Core i7 and 256GB solid-state drive.
Cons: Dual-display seems needlessly redundant and doesn't always work smoothly. Trackpad required driver update to be usable. Short battery life. No touch on interior screen.
Conclusion: Processor The i7 version of the Taichi 21 costs a steep 1600 Euros (~$2068). Would a cheaper i5 version for 1300 Euros (~$1680) be enough (128 GB SSD)?
