Uhm.. I have three.
I have a first generation iPod shuffle (the one that looks like a white pack of gum, not the smaller clippy ones)
A silver second generation Nano (which I, uhm, lost. It's somewhere in the house but I can't find it. Poltergeists, I say) which I got as a gift from my mom for getting my Masters degree.
A refurbished 3rd generation nano video that doesn't work for video and restarts if you actually try to find a specific song on it, but which I got for $3 (no lie) and which works in my car on shuffle play, so it's like my own little radio station. I put in all the songs, I just don't know which order they'll come in.
My husband has a 2nd generation nano.
I desperately want an iPod touch (well, really, I want the iPhone, but not until I can have a service other than AT&T with it) but that'll have to wait.
