It may be hard to believe, but it's already been a decade since the iPod came on the scene. With the ubiquity of today's Apple devices, it's hard to remember a time when the company was mainly known for its desktop computers. Yet, when the iPod was first introduced in October of 2001, it was one of Apple's first forays into the as-yet relatively unexplored area of personal digital devices.

With the introduction of the iPhone and iPod Touch, demand for the iPod Classic, as it is now called, has waned and it's hard to recall the frenzy that surrounded the release of the earliest models, outdated as they appear next to their successors. On Sunday, the little bastion of digital audio turned the ripe old age of 10, and we thought we'd take a stroll down memory lane to reminisce on how far it's come.
