What's this from Microsoft?

Wow Engadget spotted this interesting news that today Microsoft officially flipped the switch on the buzz machine for their Origami Project -- an atypical viral marketing manuveur for a company whose products are usually known about years ahead of time. Now, here's the tricky part with these pictures -- what's with the keyboard and stylus? Because the last time we checked, their Portable Media Center (PMC) OS didn't have (known) support for touchscreen and keyboard input. So is this some new portable OS platform running on CE.net? Or perhaps it's just a fat little Pocket PC device with some media software? Or something totally different -- could Microsoft beat Apple to the punch with the first serious touchscreen portable media device? Or maybe, just maybe, it's that ultramobile lifestyle PC" I am very curious to see what this turns out to be.
