Computex is Taiwans biggest annual exhibition of new technology and Asus is traditionally the company that makes the splashiest announcements at its outset. Keeping that spirit going, Jonney Shih has today revealed a new Transformer Book V, which runs either Windows or Android, in either laptop or tablet mode, and adds a dock for an Android smartphone on its back. Its an expansion of the Transformer Book Duet concept, only this time the Android part of the operation is handled by a 5-inch, Intel Atom-powered smartphone. The Book V is smaller than the Duet at 12.5 inches and gives a choice between running Windows 8.1 or Android 4.4, switchable nearly instantaneously via a dedicated button.
