My iPod does handle podcasts, but doesn't have wifi. It also lives on the car. So it is just a minor hassle to unwire it all from the car, download podcasts onto pc, sync the iPod then wire it all up again - every week. Not hard, just irksome. At ake's almost suggestion, I have now set my phone to download the podcast automatically and then the bluetooth connection in my phone plays over the car's speakers.

It is an ancient iPod so in those days they had 160Gb memory. As far as I know they have never produced anything that big since.
