I have an iPod Shuffle my sister got as a bridesmaid gift, and gave to me. It's OK, just plays music. I tried putting a book I purchased on iTunes on it, but it would only play so many chapters and won't read the rest.
If I'm at work I listen to music on my computer, if I'm in my vehicle I listen to XM radio, and if I'm working out they have televisions on the equipment so I watch TV.
There is no screen on it, and you can't see it through the computer as another drive, I really have no need for the shuffle.
I have a couple co-workers that have nano's and love'em.
