Just out of curiosity, how do you feel you rate when it comes to common sense and the ability to reason?
Dude- relax.
You stated your opinion. He stated his.
Look, if anyone wants to buy an imac that may/may not be plagued with manufacturing flaws, here's what I'd recommend:
1. Buy in-person from an Apple store.
2. Tell them you will need to open it up to check for monitor flaws after you purchase it.
3. Open and inspect it.
4. Demand immediate replacement if flaws are found.
5. Open second computer and inspect.
6. If second computer has issues, demand your money back.
7. Take your money elsewhere- Mac Mini, Mac Pro, buy used, Hackintosh, PC, whatever.
I was lucky and received a perfect i7 2.93, which I do recommend, as its a very fast computer and has been a wonderful purchase. But I would have been mad as hell if I had received a lemon. After 2 or 3 that would be it for me. I would get something else.
But if you can't get a perfect one, don't get pissed off at random forum members who don't agree with you and can't do anything about your problem. Let Apple know your disappointment with your voice, then do what any smart consumer would do- let your wallet do the talking and buy something else! If the numbers of faulty returned computers really are significant, Apple will definitely get the message.
