In January, 2004, Apple released a miniaturized iPod model, appropriately called the iPod Mini. Because the device was teeny, it didn't have room for a lot of controls and the click wheel was born. It was essentially the scroll wheel converted into an area-sensitive, control button. The original iPod Mini came in five colors, was composed of a sturdy anodized aluminum shell and had 4GB of storage. It initially cost US$250 and consumers gobbled them up.
