You don't need to have an IPod to hear the Podcasts.
You can listen to them by clicking and hearing in your browser, or you can download the MP3s and listen to them on your own time.
It's your prerogative.
Let's say it's getting late and you want to nosh on some nice pretzels while listening to Todd and Rachel's great new Podcast. You can do that. It's just that free a country. Unless you're listening in a country that is not free. That's cool too.
