Are there any really good iMac's out there that don't have any of the problems that seem to be frequently reported? I just received my 2nd attempt from Apple to provide me with a worthy machine (1st had the grey bar & yellow tint) and no luck, got the noisy HDD issue, yellowing, and bad backlight bleeding. This is turning into the biggest waste of time and if it wasn't for the fact that I really want this machine I'd bail completely on it. Am I just being too picky on these issues that don't compromise performance or should I try again? Is anyone actually getting a good machine? Fortunately, I am leaving town for 2 weeks so another return wouldn't be a big deal but I'd hate to think I'd get a worse machine than what I have now. Thanks!!
