Seems like déjà vu but the concept of marrying an eraser with a scanner is a very good one. The ES-X not only erases the whiteboard but also transmits the scanned content to a laptop. It can also post selected portion to Facebook (and hopefully other social mediums), but the point is to make it easy for students to take notes. I am all for devices that make school life easier, what do you say?
