Like the many that said, you did have some genuine issues w/ ur laptop. But I'm gonna be blunt here and tell some of you straight up that u're too anal when it comes to your laptop.
Yes, it's a precision tool, yes you spent a lot of money on it, and yes we all want the machine to be perfect. But the reality is, it's likely not going to happen to most of us because Apple, like many other company is for-profit, and to make a large profit, you need to minimize production costs. I'm sure Apple or anyone else can dish out a "perfect" machine, but it'll cost you your first born or kidney. Compared to many other laptop manufacturers, I feel Apple is really top notch when it comes to value, style, functionality, and quality.
With that said, I keep finding myself running into threads where I feel people are expecting a whole lot more than what they should be receiving. Apple is a great company, it's not perfect, but it strives on phenominal products and customer service to keep your coming back for more. But it seems as though a significant number of their users expect their machines to be surgically perfect that any sort of imperfection signals an alarm. Some large issues such as the battery recall, random crashes, and discoloration should be acknowledged and fixed, but there are so many cries of insignificant concerns that I feel Apple has been way too generous about. It seems as if some people are taking advantage of their goodwill to keep their customers happy.
It's really easy to drown one-self to inspect every millimeter of the notebook and scrutinze every small flaw. And it's also very tempting to use that to your advantage since Apple typically has very good receiving customer service. But one has to see the glass half full than empty. And take a step back and objectively ask if the concern is truely significant to the degree where it's unacceptable and would affect productivity or function. Some would say it's relative, but there is a fine line and common ground where the concern/issue is legitimate or not.
Yes, i spent 2500+ on my mbp in Feb., yes it has flaws, yes the whine is repaired and runs cooler, yes it still has problems, and yes I do want my machine to be perfect. But those "flaws" are so miniscule that it doesn't warrant a call to AppleCare.
Love your mac. (Poolin, to make you feel better, my mbp which costs more than the mb does not seal perfectly, isn't 100% silent, keyboard has different size gaps, came w/ a few small scratches on the cover, has slight flickering screen in the dark, and some other stuff i forgot).
I'm sorry you were not able to get a "perfect" machine, but I don't think there is anything else we can do to help you here
I do have one recommendation for you. Have a friend purchase a MB for you to avoid your bad kharma and after he receives it, have him convince you it's perfect and you ABSOLUTELY have no need to check for imperfections (because the mind sees what it wants to see). And discipline yourself to ONLY love ur MB and not check it for any flaws unless it's extremely obvious like discoloration or battery exchange.
