So today while I was forced to goto the mall, i went to mac store while everyone else was buying their crap. I was toying around with a 2.0 white macbook and surfing around on youtube just looking at random videos (had to watch the mac saber battles!). The volume was at the max and I could already barely hear the videos. Then some guy across from me with a macbookpro 17'' starts listening to some rap music and TOTALLY cancels out all my sound. Could not hear a thing! I even tried putting my ear up to the MB and was only barely making out the sound. The equivalent (in my opinion) of the macbook max setting on sound was like my a 12'' PowerBook with 6 bars!
