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.

I would love to see the computer interface of "Minority Report" implemented. Shouldn't be that hard to do, except for the translucent holographic displays :)
