Don't know about the buzz, but the weird off-balance sound of the 15" model comes from the 3rd speaker. You have sort-of a subwoofer in there. Of course "sub" means here more "sub-high". Apple themselves call it a mid-tone-enhancer or something like that. It's placed on the left side and emits its sound through the left grille, so sometimes it seems as if all sounds come from the left. It's not a perfect solution, but at least you get a fuller sound. If you step back and listen the PB has a really great sound for a notebook. If you're nearer it sounds disturbingly off, though. Steffen -- Steffen Barabasch (mailto:TheMirror at westend.com)
