This is a great talk from Michael Dertouzos about the possibilities, but unfortunately still didn't happen as per his vision.

"The idea is not for you to go to the temple of the computer, bow and lean forward to start doing things, but lean back and start an interaction that is as natural as going to the refrigerator for your milk"
