The iPod Shuffle hit the scene in January, 2005, and was instantly beloved by two sets of users -- those looking for a cheap entry-level iPod and music lovers on the go. It came in 512MB and 1GB models and was Apple's first flash-based MP3 player. The iPod Shuffle embodied minimalism. It had no screen and one playlist, which could be randomized (hence the name, Shuffle). Its included lanyard was intended to be worn as a necklace but thankfully that fashion never caught on.
