Drones are great for aerial photography. But you can do much more with them. It is not crazy to think that a drone will be able to walk your dog for you or even deliver your packages in the future (Amazon is already trying to pull that off). Jeff Myers has posted a video that shows how you can walk a dog with an AR Drone. You can track your pet and walk it from your handheld device. Not suggesting this is something you should do, but the option is available to you.
