It was once a hard choice between Dell XPS 12 and
Asus Taichi 21. Now I think I prefer the former one. The configurations for both ultrabook are very similar, for example, both have 4GB memory, 128GB hard drive and Intel Core i5. I like that Asus Taichi has a Wacom stylus and double screens, which makes the choice harder. However, the prices and screen sizes for the two helped me to make the decision. The price for the 11.6 inch screen Asus Taichi 21 is almost the same as the 12.5 inch XPS 12 while the price for 13.3 inch Taichi 31 is much higher. 11.6 inch is a little smaller for a laptop but is all right for a tablet, so I think 12.5 inch is just the right size for a convertible ultrabook. Other advantages of XPS 12 over Taichi 21 and other competitors include much longer battery life, and the rather unique way to transform into a tablet.
