My worry though is that when Windows fucked up, Mac OS was a viable alternative. Now that Mac fucks up, what's the alternative? Linux has its own challenges.
Windows is absolutely not an alternative. The UI degradation we're complaining about in the Mac has already happened in Windows - I mean they've now got 3 different UI paradigms for system settings and the newest one is this disgusting phone-style UI full of whitespace. Ads and "suggestions" everywhere don't help either.
