I am a huge fan of the Art of Product podcast: it is great entertainment and so valuable hearing Ben Orenstein and Derrick Reimer openly discussing bringing life into their businesses. Tuple is an amazing product, truly best of breed, and I have high hopes for Mightycal to reach the same heights in its respective market!

As usual, Ben Thompson does an excellent job of both going through the history of Apple and Mac OS X while placing it in context.
