But another one of his manifestos was that modern computers are really quite annoying . You have to sit at a computer terminal and hunch over and contort the computer, whereas if you have a wearable computer and you were on it, the computer's shape contorting to your form, you'd be able to walk around. And whenever you come up with that idea as you walk through the woods or you think about something, you're able to write it down. This is from (PARC Research scientist) Mark Weiser 's comment -- that the best technology should get out of the way, let you live your life. And he called it calm technology -- this technology that recedes into the background when it's not needed and processes information. And when it is needed, it intercedes into reality and then actually shows up and you can interact with it. And I think this is where we're trying to go with computing. In the 70s at PARC Research, they had this idea that the world would be full of pads and tabs and little devices -- which is now what we have. We have sensors and
