Nexus 4 Glass Back

This is just a general question for anyone who bought or is waiting to buy a Nexus 4:

Are you not worried about that glass back?


This is just plain curiosity, I'm not really considering buying it. But when I read the review on here and Josh described how easily he had defaced his own, that was a big red flag for me. Especially with my experience with the iPhone 4's back.

So, is this not an issue for you guys? Or is it that you find the rest of the phone/its price to be worth it.
