Look, I really hate to go into some meta-crap here, but really, you are just looking silly now. You yourself even said in this very thread:

I knew that moisture could be a problem. I'd never heard of heat before.

I'm sure you'll now come up with some way of saying that a problem does not constitute a complaint, that moisture is a problem but heat isn't or that it's only a problem on the iPhone, not the iPad ...

I wasn't even saying that it was a problem in the first place, I was jumping at your comment that it could not possibly be seen as a negative thing.

Full disclosure: I have pre-ordered one (Europe).
