Ok SO, I got my i7 and I did all the tests. After not having any flickering, no yellow tinge and no loud hard drive, I almost gave up and declared my Imac perfect. After a week or so of waiting for a chance to complain, I was about to announce that the war was lost. Just then, I noticed something unacceptable in a 2000$+ machine. There is dust on my screen! What gives? This is major flaw. Obviously, when I pay 2000$+ for a machine I want it to be dust proof. It's obviously broken. These i7s have so many issues I can't believe it. I don't think I'll ever buy apple ever again. This spec of dust on my screen makes me want to vomit. Anyone else on here having this problem?? I read somewhere that something like 789 out every 793 Imac owner are reporting this newly developed, major issue. Personally, I'd rather get thrown into an industrial sized garbage compactor than have to stare at a dusty 2000$+ computer. You think Apple will send me a new one?
