Ipod - Ipod Nano

The iPod nano is a mid-range iPod portable media player designed and marketed by Apple Inc. It was first introduced on September 7, 2005,[1] and combines features of both the iPod shuffle and iPod classic. The nano uses flash memory, like the shuffle, but with a miniaturized version of the color screen and click wheel found on the iPod classic. The battery and other internal parts were also reduced in size from the mini.

Instead of the hard disk used in the iPod classic, the nano uses flash memory. This means there are no moving parts, making the iPod nano immune to skipping.

The iPod nano works with iTunes on Mac OS X or Microsoft Windows (third-party software is available for platforms that Apple does not support). It connects through the same proprietary dock connector as the third-generation iPod, the fourth-generation iPod, and the iPod mini, using a USB 2.0 port on the user's computer. Although it uses the same connection as Apple's FireWire iPod Cable and can charge its battery over FireWire, the iPod nano does not support synchronizing over a FireWire connection. The iPod nano includes a stop watch and a multiple time zone clock function. There is also a combination lock feature that makes use of the click wheel to lock the iPod, and serves to secure the user's calendar and contact information. It was also the first iPod to include a new lyrics screen, modifiable using iTunes.

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",[17] 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 new iPod nanos also support gapless playback of audio files, a new search option, and a 40% brighter screen. The 2 GB model is 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 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",[18] thereby reducing environmental impact and shipping cost at the same time.
