Stylus control

If I ever find some spare time and want to keep my technical chops sharp, I might try writing some games for the tablet PC I just got. Robin showed me some titles on her DS at Meltdown, and I think the stylus control is very cool but is limited on such a small screen. Would using it for big, swooping movements make for better control? Likely just different. I'll maybe start with a pong/breakout/tennis type of game and see if I can capture user input for things like strength, spin on the ball, etc. (Like I'll ever find the time...)
