I'm going to keep this really short. First off, my MacBook (white 2.0ghz) exhibits the 'moo' phenomenon that we have all heard about. This is sure to get annoying in any quiet atmosphere such as a library or bedroom. Secondly, the 'b' key fell off of my MacBook. I like the feel of the new keyboard design, however when you see the two TINY, FRAIL plastic clips on the underside, one can reasonably assume that this could turn into another big quality control dilemma. I've had my MacBook since Tuesday evening and will be taking it back first thing Sunday for a quick (hopefully) exchange. I've already seen some other posts regarding the 'moo', but has anyone else had the keyboard problem with their MacBook?
