Most have heard about Amazon's plans to deliver within an hour to your doorstep using drones for anything 5 lbs or less. I can see it happening a few years down the road. With drones getting cheap and available to everyone, there's been some really cool video shot with them.
This surfing footage is amazing:

Taken on the North Shoe of Oahu, Pipeline. Great way to film surfing. Too many surfers but otherwise amazing to watch.
Some drone footage shot in Thailand:

On the flip side, I'm sure if there are too many, the annoying buzz of drones will get to people. The camera angles are great though.
