Horace Dediu from Asymco on the process of writing

Horace Dediu has an MBA from Harvard and an MS Engineering Degree from Tufts.  He studies the problems of business through an intense analysis of Apple and their competitors.  I became aware of Horace when he was a guest on the Mac Power Users podcast.  I also listen to Horace's podcast, The Critical Path.  In this episode, Horace discusses his writing process for what became known as the "Big Mac Index" post.
