This is amazing. With some camera smoothing in post production you could have shots that were previously only possible with a helicopter shot. I can see this being just as influential if not more than the gopro.
yes, but many drones like the DJI Phantom already do that, and better than AR Drones and possibly the Bebop. They also feature GoPro Mounts but are obviously more expensive if you add the cost of the GoPro.
