What Microsoft has done today is prove they're very focused about providing a top of the line personal computing experience. You can argue about server, but when it comes to applications (which are floating windows), Microsoft Windows has proven they can keep that title for their operating system. I'm glad to see them take ownership over the hardware. That has always been the black mark. I build my own PCs and always…
And in corporate America, Microsoft's Server products are near-ubiquitous. Consider that most of the in-house workflow tools at any company are built in Sharepoint -- and Sharepoint is actually a great platform for business apps (and easy to hire developers for). Exchange/Outlook/Lync is a great corporate collaboration suite that mostly "just works". And from what I've seen, Google Apps isn't really a threat for Microsoft -- it's largely just displacing Lotus Notes at the bottom end of the market.
