The electronic whiteboard promises much but is a clunky and imperfect technology.
The main problem is that it relies on a digital projector for the image. The teacher/presenter gets in the way and worse, the room's light level has to be kept low so as to see the dim projector image.
LCD flat panels are a pretty good substitute for the digital projector, and now the multi-touch lcd panel is going to supercede the electronic whiteboard. Let it happen! And fast!
The CNN coverage using this technology was impressive. John King's fingers did the work and awed everybody. However, the credit must go to inventor Jeff Han who first demonstrated this to a very impressed audience at TED.com.
