The First Generation iPod Nano has many of the same features as the larger-capacity iPods of the same time period - the standard iPod navigation wheel, color screen, user interface, hold button and charging cable. It comes in 1, 2 or 4 GB capacities and black or white colors. It acts as a sort of replacement for the larger, previous-generation iPod Mini, and has a smaller form factor and color screen. As its name suggests, the size of the Nano is one of its main selling points. Shortly after its release, Apple began shipping the Nano with suede-lined sleeves to protect the iPod from scratch damage. It has a bottom-mounted headphone port, includes a standard pair of iPod headphones, as well as a USB charge cable. It is compatible with both Mac and PC platforms.
