Macbook Air Owners

How many of you have had screens that have seemed to crack on their own?

I have been reading the Apple.com discussion forums, as well as some other Apple fan websites, and it seems as though the screen has been known to randomly crack on its own, without any knowledge of how it happened. It is hard to tell how common of an occurrence this is, just by reading threads that complain about it.

I just ordered my first Mac, a 13inch Air, and really do not want to run into a screen issue, as screens are never covered by warranty, and always considered to be a user-related damage issue. I could always return it and go with the Pro if it is a common occurrence, but i would rather the smaller body and weight of the Air.

What are your thoughts on this? Thanks.
