When my mom, an accountant, buys her next computer, it will almost certainly run Windows, because the accounting software she uses targets that OS. Accounting software is being taken over by the web. More generally, the entire financial industry is being taken over by the web. The impact of iPads and smartphones isn't a small contributor to this movement. There are enormous numbers of office workers who could very easily transition to Linux desktops with barely any notice that they did (Firefox is firefox is firefox, after all). It took a decade+ longer than most expected, but the operating system really is becoming irrelevant.
