I've seen that take somewhere too, and personally I don't think it holds water. I'm a mac/*nix user and the hardware is only part of that. not fucking using windows is a hell of a massive part of my choices. and there's basically nothing that they can do there to make a real dent
there's definitely a lot of people out there that have web-heavy/-only workflows and on paper that group could move over, but in reality fucking windows is still fucking windows and the related problems that have plagued it[0] for years won't just magically evaporate because of switching to a new arch
nevermind all the other crazy shit they've been pushing lately
[0] - think stuff like cruft buildup, spy-/track-/push-ware, etc etc
