The iPod classic features an updated design on the digital media player you already know and love. Some of the new bits include a sleek all-metal enclosure, a massive increase in storage space, a thinner body, and a brand-new user interface featuring Cover Flow. Cover Flow allows you to easily browse through your music collection by flipping through each album's cover art using the Click Wheel.
