History: The iPod nano represented a bold decision for Apple: to replace the best-selling iPod mini, at the height of its market dominance, with a brand-new, significantly different iPod model. Whereas the mini had been based around a 1" hard drive, the iPod nano was built around a 2 or 4 GB flash memory drive. The iPod nano's look and feel was more aesthetically aligned with that of the iPod color than the mini's had been. It also included a higher-resolution color screen, which, along with the remarkable decrease in physical size, helped to justify the reduction in capacity. Although the nano held fewer songs per dollar than its predecessor, Apple sold the 2 and 4 GB nano models at the same price point as the previous 4 and 6 GB mini models: $199 and $249 U.S., respectively.
