We just settled on the ASUS Eee Top (ETP1602-BK-X0045). For around $500 you get a computer, with wireless built in, and a touch screen.
The only problem so far is the aspect ration. Check-in is stretched and pixilated, but people don't seem to mind.

I make notes as I am setting the computers up. I haven't been transfering my notes though. Someday...
