i have a 512Mb mpman! i love it so much!
it takes normal AAA batteries so i've got some rechargable ones. they last about a week of listening to it about 2hours a day (my bus journey )
i recondmend one! ipods arn't all that great.....why not look at some other brands?
i really reconmend mpman! really reall ygood for what it is!
