Ipod Nano 2nd Gen

On September 12, 2006, Apple updated the Nano line. The second-generation Nano features scratch-resistant, anodized aluminum casing like the earlier Mini's design; the multiple color choices (silver, green, pink, blue, and black) mirror that of the Mini as well. However, unlike the second-generation Mini, the button labels do not match the color of the Nano. Instead, they are gray, like the first-generation Mini, except for the black iPod which has a black click wheel. The second-generation Nano features "a brighter, more vibrant display", a battery life upgrade (from 14 to 24 hours), and doubled storage sizes with the new 2, 4, and 8 GB models (compared to the previous 1, 2, and 4 GB models). The second generation iPod Nanos also support gapless playback of audio files, a new search option, and a 40% brighter screen. The 2 GB model was available in silver only. The 4 GB was initially available in green, blue, silver, or pink. The 8 GB model was initially only available in black but Product Red was later added. Apple claims that the second generation iPod Nano's packaging is "32% lighter and uses 52% less volume than the first generation", thereby reducing environmental impact and shipping cost at the same time.

On October 13, 2006, Apple announced a special edition iPod Nano Product Red, with a red exterior and 4 GB of storage. For each red iPod Nano sold in the United States, Apple donates US$10 to the Product Red initiative, while retaining the regular price of US$199.On November 3, 2006, Apple introduced a red 8 GB model, due to "outstanding customer demand", while also retaining the US$249 price point of the black model with an equally large storage capacity.

Endurance

Ars Technica conducted similar tests on the second generation Nano as they did on the first generation. In their tests, the screen did not last as long; although the Nano kept working, its screen was damaged after one hard drop on concrete. A subsequent trip through a washing machine also failed to destroy it, although it did require two days to dry before returning to full operational standards
