Focus is the key-

"Small things, but good quality" is no stranger to everyone.

iPod nano 3:(8G)

Although the iPod nano 3 is not as slim as the previous two generations, it is actually very small. The diamond-shaped edge design and extremely detailed border still reflect Apple's industrial design, giving people a lovely sense of wholeness. Compared with the first two nano's, the screen is changed to a larger 2-inch, and the resolution reaches QVGA. It can be said that this is Apple's current product with the highest unit pixel. Of course, the main reason for the bigger screen is watching video movies! The battery life is 5 hours for playing video and 24 hours for playing music.

In addition, the product accidentally added the Cover Flow interface, which can be quickly operated through the scroll wheel, with three games built in, and of course it can also be purchased from the iTunes Store in the future. What users are most concerned about and worried about is the battery problem of iPod nano. This chubby nano 3 battery can support 24 hours of music or 5 hours of video, which is not inferior to the old one.
