The lack of the remote connector found on the top of many previous models means that a number of third-party accessories do not work with the i Pod Nano; newer versions using the dock connector have been made.
The first generation i Pod Nano did not support voice recording; the second and third generation Nanos function with third-party recording attachments.
The new i Pod Nano looked alot like the i Pod Mini line.
It was available in several different colors, (Silver, Green, Pink, Blue, and Black) but unlike the second generation i Pod Mini and the first generation i Pod Nano, the click wheel is gray on the i Pod Nano second generation except for the black edition.
