Microsoft announced some days ago its Surface product . If you didn't had a look on the videos you should watch it.
Last week on Delay's blog I found a Silverlight Surface demonstration  of the "photos on a table " user interface, click here to open the live demo .
Well, it is a really cool copy of the Surface user interface, but I feel bad if I use the mouse. I think we all need Tablet PCs in the future, or let us all get one of the Surface boxes... ;)
Updated: see my extended Silverlight Surface demo with video support .
