People who live in hurricane prone areas
Should have one of those hand cranked weather radios. Relying on a smartphone to listen to FM is stupid, because what do you do when it runs out of juice and you don't have power?
Besides, didn't many stations go dark in the Houston area during the worst of the storm, and AFAIK they're all dark in Puerto Rico have been for some time. Ideally you'd have something that could pick up AM, since those signals travel much further so it isn't a problem if all the FM stations within range are gone.
