Courier is a real device, and we've heard that it's in the "late prototype" stage of development. It's not a tablet, it's a booklet. The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre.
It's complex: Two screens, a mashup of a pen-dominated interface with several types of multitouch finger gestures, and multiple graphically complex themes, modes and applications. (Our favorite UI bit? The hinge doubles as a "pocket" to hold items you want move from one page to another.) Microsoft's tablet heritage is digital ink-oriented, and this interface, while unlike anything we've seen before, clearly draws from that, its work with the Surface touch computer and even the Zune HD.
