I'm thinking of it. If I end up doing the Haute route next year I'll probably buy one and take it along if somebody else doesn't already have one. A couple of the guys I'm potentially going along with are quite talented videographers. We're discussing the potential to make a documentary style film of the whole thing, not for any commercial gain but purely for a good memory of the trip. One of the guys is actually talking to a guide at the moment about the implications of taking extra gear (batteries, chargers, the drone and my DSLR+Lenses etc).
I think they have great value, just not on a resort. Imagine if angry skier Dad copped a drone to the side of the face... youtube couldn't handle that kind of rant.
