I hear you asking, “Why would you ever need to leave the Mac, stupid? God, you’re so dumb. And stupid.” Well, those are fair criticisms. These days it’s obvious that the Mac isn’t going anywhere, so this bunker mentality is certainly an anachronism. Let’s say, then, that rather than deciding to leave the Mac, I was asked to leave the Mac. That seems more likely. One day Apple just calls me up and says “You know, we’d rather you didn’t use our products anymore. You’re dragging the brand down.” I could see that happening.
