i've been following the whine issue too. i got my mbp this monday (i ordered it online last thurs using the educational discount) I think I have the whine, but it's intermittent and doesn't stay on for long. Plus, i can only hear when it's perfectly quiet in my room. It's not too loud, but it's a little on the high pitched side, which can be annoying for some people. It's really easy to get rid of though. You just need to launch either the photobooth app or a "mirror" widget for dashboard that turns on the iSight camera, and the noise goes away. Also, someone wrote a program called QuietMBP that gets rid of it by lightly utilizing the second core of the cpu (i think). All in all, it seems to be a softwrae fixable issue and hopefully apple will take care of it soon so there won't be a need to use a ghetto workaround.
Honestly, if I hadn't come across it on the internet, i would have thought it was the fan sound and ignored it.
Outside of that, I love my mbp. It's fast and beautiful.
