Licensing for Windows isn't as expensive as some people believe. Going in with their licensing plans, their cheapest server level with support comes to about $300/year. Redhat, for support, starts at $350. Yes, it can be $500+/server if you're buy it retail off the shelf, but any sort of internet related business, you're almost certainly not going to be going that way.
