Yep. A lot of people here have trouble discerning between their _own_ personal experience and the needs of the rest of the world. I don't even use Windows, but I know plenty of people using it, and I don't see them either spending money on a Mac or switching to a tablet or a Chromebook. And I don't see many workplaces switching to Chromebooks either.
Microsoft has built a good and cheap platform for workplaces PCs and households, that's the reality. The only two real alternatives I can see right now are OS X and some well supported GNU/Linux distros like Ubuntu/Red Hat/Suse, and both have their own disadvantages (the former a significant higher cost in hardware, the latter a lack of commonly used pro software like MS Office, Adobe programs, AutoCAD and other specialized software...)
