ok here we go ipods are recharageble you only need ot replace the battery if you get water damage etc etc. with the sound quality i think the ipod is better for it but i have yet to try other mp3s. the ipod is lighter the most mp3s and can easily slide into your pocket for comfort so i guse paying $100 more than u would for a cheap 1 isnt really that bad if it is better quality.
