My day job is managing a company network of about 100 Windows clients, running anything from Vista to 8.1. I agree that Windows has gotten a lot better over the years, but if you have enough machines in one place, you see some pretty strange things happening, like MS Office breaking for no apparent reason, or an update to Office 2013 breaking Autodesk Inventor, forcing me to reinstall Inventor, thereby breaking Outlook, forcing me to reinstall Office (afterwards, both Outlook and Inventor continued to work - I have no idea why). The chance for an individual user to experience such problems is fairly low, but as an admin / help desk monkey (we have no dedicated help desk, so I am the one users call for help) I get to see all those problems. Let me repeat, Windows has improved a lot over the years, and I honestly do not know what it would be like to manage ~100 Debian or CentOS clients. I am not saying Linux deployed on such a scale on such a variety of machines would run without problems. But you do run into those situations where you have to invoke some arcane command or edit the registry on Windows, too. And at least in my experience, if that happens on Linux, at least you can look at the man page for the command or the config file.
