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.

Yes, flexible OLED stuff does exist, but there are no commercial flexible screens just yet (it's taken a while to get a stable blue-emitting polymer). I expect to see OLED-based displays within the next couple of years or so (whether flexible, roll-up displays will take off any time soon remains to be seen - they are too easy to crease and damage).
