Tablet and powerpoint

Mike Eisenberg, Professor and Dean Emeritus at the Information School, University of Washington, gave a presentation in OCLC during the week. The topic was education and the emergence of the iSchool movement. There was good and engaged discussion afterwards.
I was struck by the mode of presentation. As we all do, Mike used PowerPoint. However, he annotated the slides as he went using a pen on his tablet. I thought this was very effective, and added a helpful dimension. Now that I have seen it, I am surprised that more people do not use this technique.
The presentation was in our Distinguished Seminar Series (and slides and audio will appear soon). These presentations are held in OCLC and we are pleased to be joined by colleagues from central Ohio which can give some nice variety in discussion.
