27" Screen Problems

Okay guys, I have been waiting TOO long to get this 27" iMac that I have been drooling over since the second it came out!

So, this Christmas, I will be getting it for sure. HOORAY!

But.. it seems like one problem is coming after another with these new machines.
First it was the performance issue, well that was fixed, thankfully.
Now, I've been hearing from all over the place (even the Apple forums) that LOTS of people have been having screen problems.
From some yellow tinge, to dead pixels within just days of using that machine.

So, my questions is, if I do high-pathetically get one with some kind of a screen problem, would Apple actually replace the whole thing just because of one dead pixel?
I've heard that they replaced the ones that came in with some yellow tinge on then or whatever.
But yeah, I don't know, I really don't wanna get stuck with a dead pixel with this beautiful screen. Because nothing is more annoying than a dead pixel.
And you can't even push a stuck pixel in on Macs because of the glass.

anyway, thank you guys so much if you read this thread
Let me know what's up with this whole situation.
