Wow! Like all the other posters, I was blown away by this preview. However, after doing a little Googling, I see it's not ready for prime time yet. Notice the pre-order is for a Feb. 2016 release. Also, check out this demo: Testing the 'selfie drone' in Central Park
On further reflection, I'd wager that the demo footage was done with a conventional drone and operator. Call me a skeptic, but it might be that the demo footage is meant to show what the drone COULD do once all the bugs are worked out.
Well, according to this article that just came out in the Wall Street Journal, the US Supreme Court ruled many years ago that the landowner controls the first 83 feet of airspace, not the Feds. The implication to me is that you'd better get permission from the landowner before traversing at low altitude.
WSJ has a paywall, I could get to the article by Googling "drones boom raises new question."
