This is amazing (thanks for the heads-up TreyS). Surface is a new "table computer" that uses touch instead of a keyboard or mouse. You really need to see it in action to appreciate it. The Surface homepage has several videos that are all worth checking out.
The part I'm most interested in is the idea of a computer that multiple people can work on at the same time. I can see where a family could sit around their Surface table and plan a trip...one person could map out the activities for the trip while another books the flight at the same time. Or you could play Monopoly or any other board game, where the board is virtual, but the pieces are real. Or work on a photo album together.
Today, computers tend to isolate us from other people (not counting virtual people). I see this as a platform that will bring people together to collaborate.
It will be interesting to see the new applications created for this platform. Will this be a success or a failure? I hope it is the former! I'll be following this closely. Microsoft is going to demo this at SIGGRAPH, so I'll check it out then.
