This one could be different, though it will require a substantial external hardware investment. Assuming the price of the Parrot AR-Drone isn't too ridiculous, I'm looking forward this year to getting a small quad-rotor helicopter that comes equipped with two video camera and a WiFi hub. The flying WiFi hub lets you connect to it from an iPhone or iPod Touch and fly the helicopter by tilting the iPod while you watch the view from its nose-mounted video cam beamed back to the display! Battery life will probably be an issue since this small remote controlled thing will use its power to transmit a WiFi signal and to power the video cameras and other on-board electronics in addition to the four rotors.But still - it looks amazing. If you are "remotely" interested in this sort of thing, check out the videos. It's being developed by a French company and I guess they introduced it at CES in Las Vegas last week. They apparently already have an application developer kit so there will be various "augmented reality" apps for small-scale aerial combat along with who-knows-what.
A flight sim that really flies! How cool is that?
