An interesting article.
MP3 players aren't just for music. Many use them for podcasts and/or audiobooks as well. One can never have too much storage. It is always good to have more flash memory as long as it is cheap.
Can ipods play while they are being charged via a usb battery pack?
The things I demand in an mp3 player are
1)having a card slot
2)ability to play while charging
3)autoresume for podcasts and audiobooks
What I want in a player
1)variable speed playback with pitch correction using the original firmware
2)noise reduction settings to make noisy podcasts more comprehensible
3) use of a standard easily swappable battery
4)high quality voice recording and a mic jack
5) A built in clip or comes with a case with a built in clip
