How dare you state with utmost confidence that "Apple's do not do these things", when you can clearly see that the two previous posters (and myself) suffer from this very problem.
I have gone through 6 macbooks and macbookpros, every single one has had the unbearable whine, and 4 out of the six have had "engineering problems".
Such a display of ignorance is completely useless to those suffering defects. I know what it feels like to be told that I am "overstating" or "imagining" the problem, and let me tell you, it is one of the most frustrating things imaginable.
