iPod nano

Wikipedia notes on this gorgeous device!
The iPod nano is a portable media player designed and marketed by Apple Inc.
It is the midrange model in Apple's iPod family.
The first generation model was introduced on September 7, 2005, and combines features of both the iPod shuffle and iPod classic. It was intended to replace the iPod mini, which was discontinued on the same day.

And on-to Mk III ...
Apple updated the nano again on September 5, 2007 and made it available the weekend following.
The third generation nano features a 2-inch QVGA (320×240) screen and a shorter, wider, heavier design, with new colors.
New features include browsing via Cover Flow, a new user interface, video playback, and support for new iTunes Store games.
The nano was announced in a 4 GB version at US$149 (UK£99.99) coming only in silver, and an 8 GB version at US$199 (UK£129.99) coming in silver, turquoise, mint green, black and Product Red.
The battery lasts for approx. 24 hours on audio playback and approx. 5 hours on video playback. On January 22, 2008, Apple released a pink version of the 8GB iPod nano.
Combining elements from the previous generations of iPod Nano, the third-generation iPod has an aluminum front plate and a chrome back plate.
The nano also sports a new minimalistic hold switch, similar to the iPod Shuffle's power switch, which has been moved to the bottom of the player. The 2 inch screen has the greatest pixel density of any Apple product and has the same resolution of the 2.5 inch iPod Classic's display.
