I quite like the practical applications of drones, and hope to get a good one eventually. Using them for aerial surveillance (not in a military or security fashion) is pretty cool. I've seen then used on archaeology digs, volcano explorations, and more. I'd like to be able to rig one up to do aerial photography for when I start visiting places like Yellowstone, or the Grand Canyon...Be able to take a selfie of myself from a camera that is over the chasm of the Grand Canyon? Pretty awesome, I think!
My only concern, regarding drones, is their potential (and in some cases already applied) misuse. There have been several nudist resorts that have complained about locals flying camera-equipped drones over the resort, and that is a huge violation of privacy (prosecutable too). There are many other concerns regarding the misuse of this awesome technology, and it will take time for the world to adjust to the prevalent presence of them...but overall, I like them, and I want one.
