I think I was pretty open about the fact that it's obviously going to be our viewpoint that we don't think people should do NoSQL.  However, it's also because I genuinely believe SQL is the right decision.  There may be use-cases out there where NoSQL is a good fit, but there are also use-cases where Windows is a good fit, but I'm still going to recommend Unix systems in general.  As with all things, if you don't know why the general advice doesn't apply to you, then the advice probably holds!
