iPhone 5 Drop Tests Are In: Extremely Durable
I could write something more about this but the videos speak for themselves. You can check out the story from MacRumors which links to videos from Android Authority and iFixYouri.
Spoiler Alert: The guy from iFixYouri had to forcibly throw the iPhone 5 towards the ground screen down from chest height to get the screen to crack. His many previous attempts utterly failed to produce any significant damage.
