Joelle, I have several iPods because I outgrew the 2nd generation as well as the 3rd generation.
I gave away those two. Right now, I have a 5th generation and a nano. I used to have an iPhone, but it got stolen, and my husband bought me a Nexus One.
It isn't that I need to have tons. It is just that music and books are my thing. I don't spend money on hair, nails, clothes, or going to movies. I am now waiting patiently for the second generation of iPad. I think that will be my last.
