As of September 2011, there are six generations of iPod nano. The nano's first generation was released in 2005 and was available to consumers in either black or white and with two and four gigabytes of memory. The nano has evolved considerably since then; the current day sixth generation iPod nano now comes with between eight and 16 gigabytes of memory and more colours than you could possibly hope for.
