I have actually applied to Google Zurich (but after 10 interviews they didn't hire me) and studied a bit how the life is there. There are many advantages or living there, but the cost of life and the fact that most people in Zurich are immigrants makes it a pretty cold city where it is hard to make friends or stay for a very long period of time. I think that now your point about "tech friendly environments" is not relevant anymore, because many countries support tech companies and offer a lot of grants for programmers and tech-related activities.
