Another prototype Tablet PC

Oh to have the sort of friends Steve Paine does.  My inbox fills up with "funny" photos of dogs doing silly things, or round-robin messages of good will, whereas he gets pictures of prototype Tablet PCs.  Admittedly the latest is conspicuous for the absence of accompanying information, but if pictures speak a thousand words then I don't have to write any more in the post anyway.

Judging by the look of the stylus I'm thinking passive digitiser, although others have pointed out what looks like a trackpoint on the lower right-hand side of the screen.  Anyone know anything more?
