There have been some very interesting developments for people looking for commercial drones for things like agriculture, surveillance and real estate photography.
The DJI Inspire 1 Pro offers exiting 360 degree photography, and I imagine you can use that footage to create those cool videos you can see somethimes where you can scroll on the screen and see everything in 360 degree angles.
I guess that is what GoPro is going for with their new drone Karma, that is yet to be launched.
Cool technology for sure and useful. In both surveillance and commercial photograpphy.
Another option, but a more prosumer style drone is the 3DR Solo, where you mount your GoPro. Cheaper but still good. DJi Inspire 1 is the best commercial drone for the money right now, in my opinion, in competition with DJI Phantom 3 and 3DR Solo.
