As I was looking at this presentation, I was thinking about my own classroom.  I teach at a 1:1 laptop school.  I turned down having a Promethean Board in my classroom a couple of weeks ago.  With a tablet laptop, projector, and a document camera, it seems like the Promethean Board would have been too much of a good thing.  I do wish that I had more room in my classroom because the only practical set-up is desks in rows and this does not promote the spirit of collaboration that I want in my classroom.
