because like most normal humans I put on a ******* case on it.
I'm not sure how true that is. Of my 6 phones since the OG Droid, I've only put a case on one of them; my Galaxy Nexus. And that was only because the curve of the back of the phone made it want to slip out of my hand when I tried to hold it tight. Of those six, I've only broken the screen on one of them, my Thunderbolt, but I believe that was before Gorilla Glass. I've dropped the other ones a few times, but haven't broken the glass.
