The redesigned iPod nano has a smaller, thinner, lighter anodized aluminum enclosure. It comes in five colors and features a brighter display and up to 24 hours of battery life. Now available in 2GB, 4GB, and 8GB models, iPod nano can hold up to 2,000 songs or 25,000 photos. Seamless integration with iTunes means users can shop for music, audiobooks, and podcasts on the iTunes Store and then sync everything to the iPod nano by connecting it to their Mac or PC.
