Eat your heart out, Apple. Deep in the bowels of Microsoft, the company's brightest engineers have been working on a top-secret tablet computer called the Courier. Gizmodo reports that the design is in the "late prototype" stage of development. The Courier has dual 7-inch multi-touch screens connected by a hinge that contains a single home button and doubles as a pocket that holds items you want move from one screen to another. Users can write, flick, and draw with a stylus as well as fingers. Gizmodo called the interface, as demonstrated in a promotional video leaked to the site, "unlike anything we've seen before."
