Techno Squirrel

Okay, clearly I've been out of touch but when did these devices start invading schools and conference rooms and where was I? I mean I saw these demoed like 8 years ago but they were $20,000 and laggy as hell at that point. If you don't know what I'm talking about checkout this video ( http://www.youtube.com/watch?v=MqmrIqWQiAw ). Basically a touchscreen whiteboard/projector screen connected to a computer. It looks quite intuitive and being an IT guy I've often thought how nice something like this would be. Actually to be fair I didn't dream big when I thought about something like this, all I really wanted was the ability to push a button on the whiteboard and produce a print out of whatever I drew in marker or output it to a PDF. Now just to convice my employer to invest in one for our conference room...
