My GF gave me an AR DRONE 2.0 Quadcopter for Christmas. It's cat terrorizing flying computer with a 32 bit on board processor at 1 GHz, 1 Gigabit of Ram, Wifi, 2 HD 720p 60 fps Cameras, Ultrasonic sensors, accelerometer, 3 axis gyrocope, pressure sensors etc, and it runs Linux.
It auto lands, auto stabilizes, and broadcasts live HD video back to my iPhone and iPad which I control just by tilting.
I am loving the future very, very much.
