As well as the obvious military and police surveillance applications which these types of model are already under development for, it's the camera carrying uses which will interest most of us here. Given the demonstration in the video of its ability to return to the operator automatically under gps guidance at the push of a button, it's only a small step to being able to program it with a co-ordinate from say Google maps (within the battery power range and back of course), send it off to take some pictures, and return to you.
