Updated Microsoft has pushed back the unveiling of its mysterious Origami Project, believed to be a consumer-friendly tablet PC, to next week. The website dedicated to the project last week said we would "learn more" today, 2 March, but the site now says we'll "find out" about it on 9 March.

Next Thursday is, of course, the opening day of the CeBIT show in Hannover.

On Monday this week, a video allegedly leaked out showing a handheld wireless PC with pen input. In the promotional movie, it was used to play and record music, do satellite navigation, play games and surf the Internet remotely. Think a truly personal computer small enough to take with you wherever you, but big enough and sufficiently powerful to do big jobs, not just basic, PDA-level stuff.

As we noted at the time, this is the kind of thing Intel has been talking about a lot of late, though the chip maker doesn't believe it will have processors that can run Windows Vista on battery for a whole day until 2010.

As several Register readers have noted, the Origami website HTML refers to a "Mobile PC running Windows XP", so MS clearly isn't waiting for Vista. ®
