Hey everyone, I've been seriously considerin a black macbook for quite a while now, and with the recent update I think Im going to make the plunge. My PB just crapped out on me, bu I noticed the sound quality on my PB was a whole lot better than my friend's MB. In fact, it would get so bad, that instead of listening to music through his Macbook (or plugging speakers into it, because all it did was make te bad soun quality louder), we had to upload his songs onto his iPod and than hook it up to speakers to listen to his music. Whats everyone's thoughts on the MB's sound quality? Is there anything I can get that coul improve it? Thanks!
