It's true, my PowerBook G4 has a whine, it only occurs when i 'Get Info' on a 979 MB quicktime on my desktop, and goes away when i scrub the preview timeline. Perhaps the whine has been there all along, throughout various incarnations of Apple Notebooks, and we were being too sensitive with these new MacBook/MacBook Pros. Whine aside, i adore my PowerBook and it still never fails to amaze me nearly 18 months after getting it. Any other PPC notebooks with the whine? I checked up and couldn't find this mentioned on the first search page. Rich.
