Just got my new i7 in the mail today after waiting for the refresh for 5 months and it has that stupid high pitched noise that you get when you adjust the brightness. Im so pissed right now id throw the F*^#ing thing out the window if it hadn't cost me $2500. I returned four of these things at the beginning of the year (2 HD failures, 1 power source failure, 1 DOA), one that had the hd failure also had this same high pitched noise. I love these computers (minus the complete lack of quality control), so I don't want to switch back to pc, but im at my wits end here. Apple already gave me $150 off this computer for me trouble, but I just don't know if its worth the hassle anymore, What would you guys do? Im returning it for sure, but would you ask for more compensation, maybe a ram upgrade or something? I don't like to be the guy who asks for free crap, but the way I see it, they can give me another hundred $, or I can go back to pc and they lose a customer for life.
