I received my macbook this past friday (5/5) and I had none of the problems that were mentioned. I updated the firmware and the "cpu whine" barely, and I mean BARELY, became noticeable. The mirror widget solution worked for me, but I wouldn't even consider what I encountered to be a whine. Heat is an issue occasionally, but you need to remember a few things. A) The area above the F-keys is meant to dispell heat. B) The thing has a crazy processor in an aluminum case, it's obviously going to get warm. C) Macs run notoriously hot (I've asked quite a few Mac users, one with a 15" PB G4, the other with a 12" PB G4, both said that even before the "heat scandal" theirs ran hot). Now, if yours is running hot enough to burn you, there's an issue.. but I have yet to encounter that problem.
