I am looking for a excellent mp3 player, but one requirement would be to share my music with other mp3 players such as me or my wife would own. With the IPod's I've heard its impossible to take the music out, you can only insert or delete. With the Rio's there some type of technology that only lets you work with it for a few days before it deletes on you (thanks to Microsoft). Any suggestions on what I should be looking for and if my product exists? Thanks.
