Interactive Whiteboards - Add stuff here!

Interesting there isn't anything posted yet...if anyone does, I'm interested in knowing more about Airliners vs. Smartboards. I don't know squat at the present!

I would like to know more also, specifically if anyone has used both which they prefer and why. What are the benefits of each vs. the problems? Does one have capabilities that the other doesn't? All I know at this point is that airliners are more like a tablet pc, in that they are portable and wireless. The white board, which instead is served by having a multimedia projector at the front of the room, is manipulated on the portable airliner and displayed via the mm projector.
