I don't develop or support anything on Windows. Sure that excludes 99.9% (I guess) of career options involving a computer, but I've still found employment that doesn't require Windows. But once either Microsoft finally succeeds at banning Linux from running on desktop PCs (which is basically what this is about), or every single employer requires everyone to run Windows, then I guess I'll switch careers to farming or something.
I would bet the majority of gamers are actually on console by raw numbers. Appliances are super useful for normies.
And native desktop development is, like, 2% of enterprise development. Tops. And all the paying users are over on the mac side.
