Gizmodo has the First Details of Microsoft's Secret Tablet - Courier tablet. This is of course not a real device, and it has a lot of things that could be potentially be amazingly awesome, if it emerges and acts and looks anything like the concept video.

Of course, it looks awesome and the video shows it working perfectly for that example, but remember how the demos for tablet computers and the UMPCs that MS was all about a couple of years ago looked, awesome, yet that buzz kinda died. If they can pull it off though, and if it works in real life as well as it does for the very narrow use case in the video, hell, I'm all over it :)
