@SteveRichter: Azure and Windows are in a symbiotic and very much mutually beneficial relationship. Even though there's a lot of custom glue, Azure is Windows at it's core. The needs of Azure drive improvements in Windows itself.
Admittedly I do not know enough about it but I am anti Azure. I think Windows Server should have all the features of Azure built into it. That is a shop should be able to run its own Azure service. So I figure if Microsoft spun Azure off then Windows Server would be free to compete against it.
