I would concentrate FIRST on making a good podcast.. THEN on the novelty of podcasting off the tablet. First and foremost, you want the show to be listen-worthy. I'm not sure that I would want to use the N8x0's recording as a basis for a podcast, but it's not to say it couldn't be done. It's just that you'll probably end up with far less quality and have a much narrower breadth of sound than you would if you used a good sound card with a proper microphone.
