Using TabletPCs for studying

I love reading the Student Tablet PC blog.  This is a really interesting idea that includes the value of not just a tablet but the applications such as OneNote and how they can add value to studying.

In my life, I use OneNote to layout items I'd like to discuss during demo's.  As I am presenting I often find it would have made more sense to address things in a different order, and with OneNote I just drag and drop the list items around.  The numbering automatically updates.  I can also print or send these notes to the audience if they would like to take notes on top of the agenda.  This method should also work well in a classroom.

It would be great to hear your comments if you have other creative ways you use a tablet in a learning/teaching environment.
