I need to purchase a mobile interactive whiteboard that will be shared among three classrooms. I am looking for something with a mounted projector. I'm looking at something in the 47" range (I'm American, so please excuse my use of inches) but I'm willing to go larger. I've investigated the Eno One Mobile so far. Does anyone have experience with this, or any other mobile interactive whiteboards? I could really use some advise on this one.
