HP TouchSmart
I don't know whether the screen supports multi-touch (sensing multiple fingers at the same time), but, I didn't have time to ponder where in a Windows UI I might find something to test on.
Still, you can passably tap buttons, except even there, I tried to hit the close 'X' button at the top right corner of the screen, and, well, I couldn't. The bezel around the screen juts out at a 90 degree angle 1 or 2 millimeters beyond the last pixel, and it's a massive 1/2" or so high, so fingers can't go there. Back to the drawing board.
Still, HP makes some wonderful video ads.
PolarisMotor in Italy has some very fun-looking vehicles.
