I haven't been to a MS developer conference and saw a mix of platforms at all other conferences I've been to. Have you actually watched apple's product launches? Ever notice the media consumer is whom they are marketing to?

>OS X has shipped with a complete Unix shell since 2001. Pretty much every dangerous command you can think of on Linux will execute the same way in Terminal.

There is so much more to an OS than terminal, so it's not all that matters. I suppose if one only worked 100% out of terminal and nothing else it would be a non-issue.
