I have been thinking quite a while now about what would make the ultimate UAV flight controller.  Reading through a CES highlight story I saw the NVidia Sheild project that basically combines an Android Jellybean touchscreen tablet with a game controller.  Of course this device is "vaporware" and is designed for gaming, but it doesn't take much of a stretch of imagination to run the Mission Planner for Android software currently under development, plugging a USB telemetry link into the port on the back, and flying/driving the UAV of choice.  Closing the lid it appears to be quite portable.  It will be interesting to see what the price will be, whether the display will be readable outdoors, and when will it be available.

With the advent of cheap cellphone processors I'm just surprised that the RC Transmitter manufacturers haven't made a transmitter that would be compatible with running a ground station software.  The mating of a cheap tlablet technology with RC transmitter seems like a good idea.
