Not got an Ipod but...
I have a Creative Zen Touch with a small radio transmitter attached. That way I can move my Zen from house to car without faffing about with wires etc. I just preset the frequency on my radio(s) and tune in. A way to have your entire music collection with you in the car and at home.
I have to say it is great and the transmitter only cost about £8 inc shipping from HK.

PS: A good side-effect of the Ipod/MP3 player phenomenon is hitting the random button - it's like re-discovering your music all over again.
if anyone is needing a podcast feed reader i can vouch for "juice podcast reciever" its free and really easy to subscribe to feeds, and downloads new podcasts automatically.
i just transfer them onto my IItronics usb memory stick/mp3 player......you dont have to buy an expensive i-pod to listen to podcasts. my fave podcast subscription is the "dub session" podcast. a really good reggae show coming out of texas of all places.
