All the craze about Yosemite looking a little like iOS... Why aren't we as interested in THIS?

Redmond says Windows 9 will be one OS spanning every platform they target. Beating Apple to convergence could be *huge* for them. With the release of Broadwell machines that are as mobile-ready as any ARM, it seems every piece is falling into place for a rock-solid MS ecosystem (though honestly, I'm also as interested in Ubuntu's unification project to follow shortly thereafter).
