Podcasting is fun, although I prefer audio to video. The delays in buffering can be quite irritating sometimes. I watched a travel vodcast? about the Grand Canyon, where they were talking about the Mountain Lion. (I do have to say the buffering time was much better than the "Wedding Dance" video on YouTube). The podcast itself was OK; however, it was very fast to load, the sound was good, and was free!
I have listened to a Rick Steves podcast from an IPod on the way to Canada with my nephew. This was great, as we have very different tastes in music. I did try to find one of his podcasts on podcast.com, but got no results.
It is really cool to have so many options at your fingertips without delays.
