What a witch that lady was to you! Don't feel bad, I just found out what an Ipod and Mp3 player were only a few months ago. I ended up buying a Samsung MP3 player too. I hardly ever use mine but then I am old too.
I think that a Nano is less expensive model then an Ipod but I could be wrong. You should have called her a 'cheapskate" for having the lesser model.
