Engadget - Here at CES 2013, LG's introing a brand-new Windows 8 line: the Tab-Book and Tab-Book Ultra. As you may be able to tell from the naming convention, the devices are intended to offer the best of both worlds, offering a convertible slider form factor and, in the case of the Ultra, the thinness and lightness associated with Ultrabooks. Both models support five-point multi-touch and pack 11.6-inch 720p IPS displays, in addition to ports for HDMI and USB 3.0. But that's about where the similarities end.
