• The drones will be noisy. 
• The payloads are going to be tiny (ounces) and the containers they are held in will be clunky.
• The  distance drones travel will be short (less than a mile).
• There will be frequent failures (drones in trees and on rooftops).
• Hassles will occur (problems with government regulators, police, and nutty neighbors).
• It will seem like everything needs to be done by hand.

None of this matters.  It’s actually kind of fun to experience this and solve (t)he problems presented.
