Take a look at the futuristic add for AT&T.  Way back in 1995 they were thinking about the future.  Most of this technology exists today, but is still in the development stages.  If you can afford it the technology of the future is here today.  Things like remote control lights and cameras that are controlled by your phone are here, too bad it's just for the super rich.  The one thing that Tom Selleck (yes I recognized that voiceover!) talked about that is really about to come true is the phone watch.  Now it will be a Bluetooth add on for your phone, but I think it's going to be convenient to be able to see your messages without taking your phone out of your pocket.  Hopefully Apple will actually release it.
