I don't disagree with this. When running the infrastructure for the Blekko search engine we did the math and after 115 servers worth of cluster it was always cheaper to do it ourselves than with AWS or elsewhere, than after around 1300 servers it is always cheaper to do it on your own space. (where you're paying for the facilities). It was an interesting way to reverse-engineer the colo business model :-)
