AEE Aviation Technology's Selfly is a phone case that turns into a drone. Your first question is probably “does it fly with the phone in the case?” The answer is no. Which is undoubtedly for the best, since I don't think it would do a very good job of protecting your phone when its battery runs out after four minutes. Even though it is a case.
Anyway, by no means is this a practical product, but it is a great example of how drone technology — 1080p video cameras and all — is trickling down to entirely unrelated, inexpensive gadgets. Maybe one day everything will have retractable propellers. The Selfly will be available sometime this quarter for $130; that price includes two batteries.
