MP3 players can be made about as small as you could reasonably expect, yet there's a limit to how small you want something to be. But now with this new released model the size race might be over. The Walletex Wallet MP3 Player probably would be the winner.

Slightly thicker than a credit card and in the same shape, it'll fit into your wallet or your shirt pocket. So for people who love to enjoy music all day long without being bothered about carrying a bulky mp3 player or the iPod for that matter really have a steal!!! Of course the sound quality is yet to be tested, but people for whom size matters we have a clear winner.
