The iPod’s user interface was good once you figured it out. I bought a 2nd gen one, I think, because it was the only large capacity device that supported audible audiobooks, and the UI frustrated the heck out of me. I consistently had trouble navigating it.

Then it clicked, the control, no matter what it looked like, it wasn’t a d-pad. It was a weird touchpad emulating a physical dial. Which exactly nothing in the documentation that it came with mentioned.

I worked for Microsoft at the time, and took a lot of grief for not using a Zune. Except I owned one, bought cheaply at the company store. It just never supported Audible.
