My Nexus 7's Display Randomly Cracked!

So, after about 7 months, my Nexus 7 spontaneously combusted. Okay, it didn't "combust," but I had my Nexus 7 sitting on a shelf for about a week, and when I finally went to pick it up yesterday, the screen was shattered.

Now, it was perfectly fine beforehand, so how does the screen just spontaneously shatter like that? Is this a problem on Nexus 7s, or is this a fluke?

Also, I'm guess that this is not covered by ASUS's 12-month warranty. Has anybody had luck returning it to ASUS to get it fixed for free—in the case of spontaneous shattering? If it's a known defect, they should repair or replace it for free, right?

I'd like to send it back to ASUS, but I know that the warranty states that if it is deemed to be from user abuse or whatever, they will repair the device for a certain price that's more than likely more than the Nexus 7 cost to begin with. Also, if I were to refuse the repair, that there could be a $100 evaluation free regardless. And then there's all the shipping fees I would have to pay.

So, guess I'm just wondering if anybody has had experience in this, and what happened, and what recommendations you may have. I don't have the money for another Nexus 7, but I also don't want to waste money on shipping/evaluation fees or anything.

I know there are some guides on replacing the LCD display, but the price of the display is still $100 or more!

Thanks!
