It misses a key decision factor: Is the technology going to be a competitive differentiator for your company. If so then having it in-house is much more important because your business strategy is going to be closely tied to your development work as the company evolves. However if you primarily compete on other factors (i.e. content, sales ability, marketing, etc.) then outsourcing the dev work and focusing on your core competency makes a lot more sense.
