Almost as cool as a jetpack, the AR. Drone.
Have you seen this thing? A remote controlled four prop drone plane that you operate via the iPhone!Watch the video and tell me that is not impressive. What kid would not love to have this. The Drove has a camera on it and is broadcasting via wifi to your iPhone.
It is listed at $299 on Amazon, a little pricey but it looks to be worth it.
The iPhone app that is tied to the game.

I picture me streaming video from the drone to the screens on stage when Allison and I are doing our platform talk at ImagingUSA this year. Then I picture it suddenly dropping on someones head and then I picture the word lawsuit. BUT... you have to admit that would be pretty awesome.

ha. It is cool. It has nothing to do with Imaging or your talk but imagine being able to show your new toy off to a whole crowd at once LOL... love your thinking. Ps. Good luck getting that one past Allison, but I dont like your chances.
