While folks await the opening of CeBit and what Microsoft has to say about Origami, take a look at ZDNET's video peek at an Ultra Mobile PC. Nice overview of what is possible with these new devices.
You can also see some early CeBIT pictures from Engadget, although I don't think I'd pay too much attention to their very quick (5 minutes they say) assessment. They must have been in a hurry to get to dinner.
