You may think that all you need for the ultimate iPod setup is an iPod, iTunes, and a killer collection of digital music. But techies in the know realize that the iPod has the potential to be much more than a mobile music machine. Indeed, a plethora of accessories are available to upgrade the player's audio quality, unleash its audio for all to hear, transform its owner's in-car listening experience, and (of course) protect its physical beauty. Whatever your budget, you can find the perfect accoutrement for the iPod lover in your life.
