I've not had a cover on an iPhone, and have owned every iPhone since the original. I've broken 1 (and a case wouldn't have saved it..it got run over). Not everybody is fucking gorilla handling their phones. Some of us can have nice things...
I used to throw my blackberry at people. One time it missed and it skipped over a natural slate floor like a pebble over water - no damage. Also dropped it on cement many times. Never a scratch (sometimes had to pop the battery back in)
Compared to my first iPhone 3G w/ rubber+shell case which I absolutely demolished in my jeans longboarding my first time. I still feel bad about that.
At some point phones became less durable than my own body. It's just different.
