I like my MacBook Air (my hands are soaking in it right now), but the speakers suck. I have never been able to get much volume out of them. Until now.
One of the winners of the MacWorld awards this year was Boom, a “volume booster” for your Mac. Works like a charm! It easily doubles the volume of the speakers, making it practical to use the Air to watch, say, The Daily Show, without having to don earphones. Well worth the $5 to crank your Mac up to 11.
