Apple iPod nano (Fifth Generation/Video Camera) features an aluminum and glass case -- just like the iPod nano (4th Generation) that it replaced -- but the nine colors offered -- silver, black, purple, blue, green, yellow, orange, pink, and (PRODUCT) RED Special Edition -- have a "glossy", rather than matte, finish. It has a larger, higher-quality 2.2" TFT display (240x376, 204 ppi), and an integrated microphone and speaker as well.

For storage, it uses either 8 GB or 16 GB of flash memory, capable of supporting 2000 or 4000 songs, 7000 or 14,000 photos, and 8 hours or 16 hours of video, respectively.

Beyond the glossy finish, larger display, and audio capabilities, the iPod nano (5th Generation) also gains a video camera -- capable of shooting H.264 VGA 640x480 at 30 FPS with AAC audio (it cannot take still photographs) with a variety of basic real-time effects -- a built-in FM Radio with "live pause" (allowing one to pause and rewind up to fifteen minutes) and "iTunes tagging" (tag a song on the radio for later purchase on iTunes), an integrated pedometer that tracks steps and calories burned, VoiceOver technology -- previously introduced by the iPod shuffle (3rd Generation) -- to speak the name of tracks and artists to you, and "Genius Mixes", which makes an effort to "find songs that go great together".

Battery life for music is 24 hours and 5 hours for video playback, equal to the "fat" iPod nano (3rd Generation) rather than the iPod nano 4th Generation which had reduced battery life.

Note that the color yellow -- likely due to lower demand -- as well as (PRODUCT) RED only were available direct from Apple.
