podcasts, audio books, music of course. I have a bunch of ambient music on there for work. (outcalls.) so I can set up at the client site (massage therapy) and have "massage music." I also have a flat set of folding Altec-lansing speakers.
It's not an IPod though. It's Creative's Zen MicroPhoto. 8gig flash drive. I love it. The only drawback to the Creative is that all (and I do mean ALL) of the accessories are made to fit the IPod.
Like you, I don't listen to music that much... mostly talk radio, NPR, lectures, etc. MP3 players are great for that, but I don't know that I'd spring for a 60 gig HD unit just for that.
P.S. what Terry said? Ditto for the Zen. Recorder, easy drag and drop file transfer, supports many formats, Radio tuner, easy menus...
