There's a call for papers for a conference on the use of tablet PCs and pen-based technologies in education. I think that this is the 3rd meeting of WIPTE. Past proceedings turned into manuscripts. Though I have not attended, this conference looks promising.
"WIPTE is open to anyone with an interest in instructional technology. A wide variety of disciplines are embracing Tablet PC's and similar pen-based devices as tools for the radical enhancement of teaching and learning. This conference is intended to leverage this shared passion and to identify best practices in the educational use of pen-based computing so that all educators may benefit from this next generation of technology. Each WIPTE paper presentation includes an assessment component as an important part of the presentation. The WIPTE program also includes keynote talks, poster presentations, vendor booths, panels, and special sessions."
