Update 12/12: these are now out-of-stock. Apple.com again has their refurbished iPod Nanos starting at just $79 for the silver 2GB model. All colors (silver, blue, pink, green) are available in the 4GB size for $99, and the 8GB black Nano is available at $149. The 2nd generation Nano is 40% brighter than its predecessor, 0.26" thin, comes with the standard one-year warranty ($39 for two-year), and has extended battery life. The newer 3rd generation Nano is available at $149 for a 4GB silver model and $199 for the 8GB model (available in five colors). Shipping is free from Apple, though sales tax is charged to most states.
