> Why it is hard for a mature company with legacy systems to create a new operating system is a difficult thing to explain. My theory is that you can't really _plan_ how to create and spread an OS: You need to put a dedicated enough person with enough time to write an interesting prototype that would brings you a subsequent advantage. And of course, you need the peoples that will judge wisely about the long run future of this prototype (remember Linux being considered bad?). After this, the prototype have to be mature enough for developers to and hardware makers to support it. That's a lot of _if_, and I suspect most OS (and in some way, softwares and language) are spontaneous creations that answer a need and become _good_ as a consequence of being used.
