Here are some helpful, short videos that show what Microsoft Surface can do.
Surface is a 30-inch tabletop display that enables multiple people to interact with digital information. There is no mouse and no keyboard. Instead, you just grab digital content with your hands and move information between objects with simple gestures and touches.
It will be great as human to digital interfaces move more and more in this direction (and hopefully Apple will take the lead here; the iPhone is a great start). Mouses and keyboards are a limiting factor on how quickly and easily we can deal with information. We need digital interfaces that are more like the physical world if we are going to be able to keep up with the pace of opportunity and stay sane.
There will always be some place for the keyboard — namely, when you actually need to type. But a primarily touch-based, multi-dimensional interface for interacting with our computers will make both the routine and creative dimensions of work much more smooth and intuitive. The result will be that we can focus more and more on the actual work, rather than operating within the limitations of our interfaces.
