Reality
Why do people still run Windows? The answer is "Marketing." That and the 100s of thousands of businesses that run software that they won't spend the money to update or port to anything else. (or for which alternatives on other platforms don't exist) And the MS-based infrastructure in place with the blood still wet on the contract. Stuff like Exchange, Azure, SharePoint, OneDrive, Skype. And now that businesses are using Skype for their main telecom instead of just messaging, the pit grows deeper. The unholy partnerships between big players like Intel, Dell, HP and MS also serve to discourage anyone who dares to think differently when choosing a processor or OS.
I personally use Linux as much as I can at home, and would love to see it more in the home and workplace on desktops, but don't see it changing anytime soon, at least in the US, unfortunately.
