The model I purchased was a Blue 2nd generation iPod Nano with 4Gb of storage.
I have already almost filled the unit with my stuff.
I started with Pink Floyd’s – Echoes: The Best of Pink Floyd, the some other stuff including Ministry of Sound, M-People, Mike Oldfield & Jean Michel Jarre albums.
To do with Amateur Radio I added a Morse Code tuition course, but realised this would be a problem when I used the random shuffle feature. A program was soon found and the files converted to AudioBook format. This took over an hour, but now happily enjoying my morse training.
Other features have also been put to use, including my contacts, and calendar events.
