Can't decide between an ultrabook and a tablet? Asus thinks you shouldn't have to--the Taichi model, announced at Computex, touts a tablet-like touchscreen on the exterior lid and another, independent screen on the interior lid. Opened up, it's an ultrabook; closed, it becomes a tablet. Taichi will run on Intel's third-generation Ivy Bridge processors and clearly has the Windows 8 Metro interface in mind. The company has yet to announce pricing.
