Battery seems to die quickly.

The 4th-generation iPod nano, released in 2008, was important because it introduced Apple’s tall, curved aluminum redesign for the nano line, showing how the company kept refining even its smaller products with a more polished industrial design. It also helped carry the iPod brand through the late 2000s by combining a very compact form with features like Genius playlists and video support, reinforcing Apple’s dominance in portable music before smartphones fully took over that role.
