Back in June of 2012 Asus unveiled the Transformer Book, a (at the time) unique Ivy Bridge Ultrabook convertible with dockable keyboard. The Transformer Book created quite a bit of excitement and interest as a device that could function as both a tablet and a powerful Ultrabook laptop. We knew we’d have to wait until the launch of Windows 8 before the unit came to market. But when that date, October 2012, came and passed, we started to worry about the Transformer Book. Now, 9 months after its original announcement, we’re wondering if the mythical Ultrabook convertible will ever make it to market.
