Of all the Brando products I've seen this is the one I'd be most inclined to use. The Brando USB MP3 Player has a tiny memory card slot that can read music stored on your MMC or SD card. Depending on how big a card you insert, you can also use the player as a portable hard drive or just as a means to shuttle photos from your memory card to your computer. Sure, it lacks the fancy features of other MP3 players (there's no LCD, no FM tuner, no recording capabilities), but for a bare bones second player that you wouldn't mind losing, you can't top this $15 player.
