I've seen them take crazy falls without breaking, (although the 172 story takes the cake, and I'd love to hear that story!) but then pop on a 2-foot drop where they land just right. Last breakage was 2 feet onto gravel. No doubt the life-proof cases and otter boxes help, but if I have to put it in a rubber case to keep from breaking it, I'm not going to carry it. I just don't need a phone that badly. I'm aware that I'm the exception on that though.
