What can this $10000 drone do what a $2 alarm clock can't? (Except of course send all papers on everyone's desk flying, and be a general hazard for people (hard hats required?).)
Surveillance? They've already got cameras for that. And I don't think it would take any effort to eliminate a drone if you're really up to no good. Just throw a net when it's looking away and watch it crash.
IMHO it's all about trying to use buzzword tech. I'm surprised the drone doesn't have an AI too...
