Technology in movies and tv

What have you seen in a TV or Movie that you wish were a real technology?  It doesn't even have to be in a futuristic setting.  The wireless communication sunglasses from Mission Impossible 2, or the car's features in Die Another Day, for example.

The obvious choice would be teleportation - talk about convenience - but that's not likely to be achieved in our lifetime, if ever. There were some great ideas in Minority Report, and not even the big stuff like the hand-manipulated computer screens - check out the self-updating electronic newspapers and other little details they dropped in there. We're not too far away from having commercially-viable flexible screens.
