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.
