>when was the last time you knew someone that went out and bought a Windows-based computer for anything other than gaming?

I'm sorry, what? I don't know if this is because of the developer-bubble mindset on HN (or the wealth gap that comes with that), but Windows adoption on the consumer level is around 70% and close to 90% on the business level. This actually falls short from what I see anecdotically (I don't live in any North-American / European country), which is close to 95% of Windows adoption, in general.
