Scott Adams imagines the future of the cell phone:

I was thinking about how different our lives will be as cell phone technology continues to improve. Someday your phone will be your only computer, and your home will have a screen in every room that senses the proximity of any phone that approaches. Push a button on your phone and it will take over any nearby screen to display a movie, recorded TV show, or music video. You could browse the web on the big screen, or create a Word document. You might want a wireless keyboard in some rooms, but for most applications your phone would control the cursor and allow you to do minor typing.

I've always wondered when the wall screen would come into mass use.
