The iPod Nano has a gorgeous, superslim design with a bright, photo-friendly screen. It is easy to operate and works seamlessly with iTunes and the iTunes Music Store, which has the world's largest selection of music. It boasts a nimble processor and system performance with no skipping, thanks to flash memory.

The iPod Nano suffers from unspectacular battery life, and though the device is durable, it scratches easily; blemishes show up more drastically on the black version. The Nano is pricey in terms of gigabytes per dollar, and its 4GB maximum capacity is not a good fit for many power users. The player skips many sought-after extra features such as FM radio and A/V-out, and it doesn't work with Camera Connector. The USB power adapter ($29) is not included.

Thanks to its limited capacity, the gorgeous iPod Nano isn't for everybody, but it sets the standard for MP3 players to come.
