roni - shuffle - podcasts - do it!
That is what I use my (1st gen) shuffle for. It is so great to listen to shows of interest, with all the 'TiVo' time-shift-pause-replay advantages. And, like the web, there are so many niche podcasts. If you have a hobby, there is a podcast for it.
It seems to work better for me if I just load about 5 or 10 at a time. Easier to keep track of what was listened to or not.
A few of my favs:
Science Friday - Making Science Radioactive
Ockham's Razor
Living on Earth: Sound Journalism for the Whole Planet
KCRW's Good Food
CraftBrewer Radio (beer homebrewing form Australia)
I should subscribe to many more, but I barely keep up with these.
