my 17" unibody MPB is faulty as I noticed the backlight bleed issue and also the gap between the lid is quite big. It's the 2.66 GHz version with 7200RPM HD... do you think if I ask Apple for a replacement they will give me the newer 2.8GHz 500GB HD with 7200RPM? or do you think they've still got the 2.66 GHz ones in stock?
