>Mono actually works, today. It's hype is not ~5 years ahead of an actual implementation. It's not continuously waiting for one more generation of tooling to settle down, or one more standard to be decided or API to be implemented. Its "Getting Started" examples actually compile and run, consistently.

Funny, because "it just works" has never been the case for the entire existence of Mono. Always a little behind, always all kinds of obscure bugs and unfinished implementations, etc. Even the commercial Xamarin offerings suffered from those.
