Its apiece of friggin glass and electronics what do you expect to happen to happen when you drop it? To bounce? Get smart people and get protectors on your devices!
You seem to be assuming that we're all dropping our devices off of a cliff and wondering why they're not surviving. Let me enlighten you with some well needed education on the subject.
Monday morning I was at the kitchen counter emailing a co-worker. I walked out the door, to my car, and got in. When I placed the Nexus 7 on the passenger seat, I realized it had a crack on the screen. I retraced my steps. Email sent... left the house... took about 9 steps... and it cracked. Wait what? Yes. That's right. I did not go mountain biking off a cliff. I was not in the rafters of a factory playing Doom. I was not skiing down a black diamond course with the N7's GPS tracking my speed only to have an epic wipeout. No. I took nine steps to my car and somehow it cracked.
I had screen lift on the left side, but it wasn't nearly as high as some users had reported. Mine is from the first generation, which I believe is the C60 generation (beginning of SSN on box). It is absolutely astounding that there are these many claims in regard to screen issues. Personal opinion... I don't think the Nexus 7 screen is actually fragile at all. But it is glass, and it was mounted improperly, which likely stressed it from being not flush. Right there you have the perfect storm in regard to acquiring easy racks.
Reading all of these posts about you folks having misfortune is enraging me even more than my own scenario. I'm undoubtedly expecting ASUS to email me with the insane quote to get it fixed, but I won't live it down. Somebody will get hours worth of an earful if that's the case. Nothing enrages me more than large companies taking advantage of consumers. It's one thing if you drop it down the stairs, anybody can agree to that, but it's another to take a few steps to my car and it crack. It's also another thing (as indicated by a user on XDA forums) to physically look at your screen while holding your device and see a crack forming across the screen right then and there. THAT, my friends, is insane evidence of a design flaw. User error is user error, but a design flaw is something to get billed on the company's dime - not mine.
When I RMA'd my device, I also included a picture within the packaging showing the screen lift. I also had a typed note in there as they requested in the emailed RMA directions, which went along the lines of this:
"This picture depicts the screen lift problem on the left side of the device that seems to have plagued a good number of first generation devices. This is a design flaw that even Google has confirmed. Judging by the otherwise perfect cosmetic condition, you can confidently rest assured this device was never dropped, and even spent its short life in a leather folio case. I expect it to be fixed and anxiously await your response."
I only shipped it out yesterday so it may be a while until I have more to offer to this discussion, but I certainly don't expect it to go well.
