My friend dropped my N9 off the coffee table in the restaurant. It tumbled and the screen part did slide a little bit across the tiled floor. It wasn't even a very hard impact or anything. But my N9 ended up with 2 tiny round chips in the middle of the screen (it distorts the displayed color below it) and also a scratch of around an inch long along the middle of the screen. (You can feel the scratch by running your nail across it) This was 3 days after I got my N9 64GB. I wanted to cry.
