I've dropped my OG Droids countless times, onto ceramic tile. asphalt, concrete, with just scratches... Such luck.... I'd gotten a BRAND NEW one, and then got the X a few weeks later...It was retired to the dock with many commendations and rested peacefully on WiFi as a clock MP3 Player etc....
However... This summer.......
It was in the dock on my nightstand (which has a plate glass top), and get this, a squirrel got in the window and ran amok doing all sorts of carnage.
It knocked the OG Droid over on its face (still in the dock) and I know it wasn't even glass to glass contact... But, the OG Droid glass cracked right up the middle... One long crack... I didn't even noticed that day, saw it a few days later setting a new alarm.
Ironic.... Almost rand new and cracked... By a rampant squirrel... In my bedroom.. Sigh...
