The last time we ran into SMART Table, they were demoing a very sturdy multitouch table to a group of schoolkids in Chicago, but they're here at Macworld with some sexier tech -- 50-inch and 65-inch multitouch plasma screens that interface with any OS X machine. The tech allows you to use the screen just like the built-in multitouch trackpad on newer MacBooks, so it works in basically any app, and while it's super-pricey (they just smiled and said "thousands" when we asked), the main cost is the screen and not the touchpanel, so we could see it come down to earth sometime soon. Check the video after the break.
