Best laptop I ever had was an HP with touch screen and Ubuntu. Anything I couldn't easily do with basic keyboard controls I'd just tap the screen. Had my start bar up the right side so I could poke with my dominant hand to me very between progams. It was accurate enough I could tap to set my typing course when I was editing documents and rarely have to arrow key around.

I didn't realize how much I'd miss it until I built my current desktop. If I knew how to DIY the two 32in TVs I use for monitors into touch I would in a heartbeat.
