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. When you find the album you want, you can flip it over for the track listing. Just like you'd do with a real CD or vinyl.
