The market is packed with MP3 players of all kinds. We have Apple's iPod with delicate looks and a professional appeal as the top champion, at least when it comes to being a cultural accessory. We then have portable audio players from iRiver and Creative that are trailing the iPod in hopes of taking away from its market share, and from what it appears the trick depicts to be working somewhat. Then we have a few more hard drive players from the likes of Rio and others that are chugging along to justify their existence. That's just with hard drive players, though. Once you move to the more portable and rugged flash players, the market becomes even more complicated.
