Well, you are very good with the technology you do have. Podcasts aren't high tech at all. Simply a way of communicating audibly. Recorded books are another.
The only reason I have a smart phone is because my service provider stopped supporting my flip phone. Looked up podcast, so like a talk show? Haven't looked into any sort of digital literature. To me, if you can't smell the leather binding and feel the pages or hear them turn, then it's just not satisfying.
Most Podcasts I've listened to aren't talk show-like. You really ought to check out the 'casts made by Brian Levine. Simply a recording of the radio show, and this may be closer to a talk show than some.
I start it when I am falling asleep, sometimes it takes me days to finish one. No offense Brian! Just nice to fall asleep to pipes and tins dancing in my head.
