The Next Xerox Moment?
It's an established fact Xerox invented the first mouse based GUI. Unfortunately they failed to realise it's potential and Apple ending up stealing it for the Lisa (then Macintosh). The video on the page referenced below made me think of this defining moment in computer history, the potential of just such a gesture based user interface, coupled perhaps with a *smart* linguistic user interface is amazing. Check out the video, it's stunning!
