Anyone got a tablet PC and can recommend cool tabletty apps to make my life automatically wonderful?

ArtRage is cool, but I'm the worlds worst artist, so aside from really bad sketches for my games design documents (which I've used as a substitute for actually doing the hard work of creating the games.) that's not going to change my world.

OneNote is awesome, searching my handwriting? how cool is that, and searching text in stored images? Woo!

But aside from those two, and the brilliance of Pen Flicks in Vista, anything else world changing out there? (Pen Flicks rule, I've got the top-left, bottom-right diagonal set up to control Flip3D, and that rules.)
