Had mine on my lap when I got out of the car, went flying out of the car and landed face down on asphalt. Destroyed. It seemed ok at first, but then actually became unusable as it became less responsive, couldn't touch certain parts of the screen, and then the radio just gave out. Dropped it once or twice before that on tile with no issues. I think it depends largely on where it lands. I always felt cases were more for corner protection and keeping the backplate/battery from flying out. Screen protectors are what'll make the biggest difference, even from shattering.
