.NET actually isn't that bad as far as performance and stability go. It's about on par with Java. It's much faster than scripting languages, and significantly more stable than Ruby.
Administering a Windows stack can sometimes blow, but the languages and virtual machines themselves are relatively solid.
More stable than Ruby? Rails may have started off quite leaky, but to call anything that's been put into production in the past 2 years unstable is just plain FUD.
Yeah, so this was my point. There's quite a stretch from ".NET isn't that bad" to choosing MSFT because it performs well. And nobody has any numbers or benchmarks or anything that back this up other than anecdotal evidence.
Downvote away, but it's silly to be listing performance and stability as an advantage to choosing MSFT, when at best it seems to be on par with its competitors.
