Looking for a portable media player.

[Ocean]

well i have alot of podcasts on my computer: mp4, m4a, m4v, and xvid. and i wanted something to play them with, and i was looking forward to buying an ipod touch and software from epocrates and modality, but the ipod requires me to convert all my podcasts in order to play them. and i have around 300gigs of media.

so now im looking for an alternative portable media player. i want one that can play mp3s, m4a, m4v. and i would love if there is modality and epocrates versions for it.

i want to just pick maybe 5 gigs or so of something, maybe revision3 or iowa u emed podcasts and just drop them on the player and go.

also if there is a way to hack the ipod so it can play podcasts, i would be interested.
