You might say "really, what could a drone do that my watch/phone/iPod couldn't do?" To this end, tthe writer also makes the point that a visible drone would be good for safety, but that the menacingness of the drone should match the task. During a fun run, you want a nice day-glo critter flying around taking pictures and encouraging people. But if you're worried about safety, something that looks more like this guy might be useful.
