Charles Bostian from Virginia tech describes how he and his college sophomore students used Tablet PCs during a course. Virginia Tech had a planned roll-out of Tablet PCs in its department of Engineering. Tips from their rollout & his class:

• Planned, methodical implementation where Engineering students required of) purchase Tablet PC (Fujitsu)
• Student homework usually submitted in Word & posted up to Blackboard
• TAs grade and return papers electronically
• Dyknow used for lecture

I've been intending to to a few quick screenshots of how grading works. I'll try to get this posted in the next week or two.
