Microsoft Surface - http://www.microsoft.com/surface/
Tabletop computers. MSFT is saying they came up with this, but I swear I recall seeing a show a couple of years ago on this and the work was being done on it at a university. Match concept up with OLED and we have something cool. Wall displays, desk displays, etc that can interact with you.

Flash replacement, very pretty demo. Love the logo. Very futuristic.
