WinXP is still the dominant Enterprise Operating system (crazy I know).
Exchange email is seen as a relic of a time gone by for new companies and something that admins usually hate in large companies. Outsource it (and I'll note that the largest reseller of Exchange, Intermedia, doesn't sell Office365).
The first windows phone I had was Windows Mobile 4.0. The flipphone handsets that came out during 6.0 were good, but every one of their gigantic, flagship, Halo devices, was terrible. HTC had some of the most badass, feature-packed phones ever, and the Operating system killed them. It's just a pile of bloat, the same way WinPhone7 and WinPhone8 appear to be. Look at the work they've done with Nokia where they basically paid Nokia billions of dollars in marketing money to attempt to promote WinPho8 and ended up hemmoraging marketshare in the transition from Symbian (Elop's "Burning Platform" memo should go down as the worst corporate writing ever, and it's not lost on me that he came from $MSFT).
I won't even dignify the surface with commentary. It was an unmitigated disaster that everyone saw coming.
Azure is only large because of promo usage. It's not competitive even with Digital Ocean in terms of scale (my personal opinion, I have no facts to back this up except anecdotes I can't publish). There's a lot of empty instances in Azure land.
Microsoft is making a lot of obvious errors. They continue to be unable to remove FUD and the Cruft of age. If they go down this path, the inertia will eventually kill them; it might take 20 years, but Microsoft is already becoming a place that finds it hard to recruit. I would argue that without their ridiculous abuse of the H1B program they would not be able to remain competitive.
In short, there's a lot of stuff to fix. The bright spot for Microsoft, as always, is licensing, but that's an ugly, ugly business.
