Hi Edie! I have only audiobooks on my Ipod, and it works great. I borrow the books on CD from the library. Then, I feed them into my computer into Itunes, then I move the whole book over to my Ipod.
Or, you can buy audiobooks on Itunes, which is not a laborious as the method I use.
Get the Ipod with the largest storage capacity you can, so you can have more selection on your Ipod at one time.
When I worked, I had a 20-something show me how to do it. Your best bet is to find a teenager to help you!
No, really, you can figure it out yourself. When you first hook the Ipod to your computer, it will automatically look online for Itunes and set itself up.
Good luck!
