undergraduate survey:ipod more popular than beer

i found a ipod with 60 system memory in my dorm,yesterday night, belongs to my roommate JinHui Wu.what a huge capacity, and it's figure is similar to the pic posted left, the same maker, apple computer inc. maybe in american college life, now owning a iconic ipod music player surpassed beer drinking as the most "in" thing among undergraduate college students.why? i don't know for i didn't really have a try with this player, that sounds nice, isn't it?
