Many have reached the "turning point" already. We are working up to wave 4 now, I believe
- Wave 1 - glued in components - making the portables, non user upgradeable caused lots of backlash. I know people who have left Apple, because of this. Personally, I am typing this out on my 2012 15" cMBP, and don't plan on doing anything more, until this one fails
- Wave 2 - Trash can Mac Pro - outdated when released, and lags FAR behind PCs for a fraction of it's cost
- Wave 3 - Ignoring Pros - This spans a number of years, but it's the biggest wave so far. The beginning can be traced back to FCPX and it's radical departure and lack of initial features. Then ignoring the pros with the trash can pro, removing ports like crazy, thin over power/cooling, not offering more than 16 Gigs of RAM on a portable until just recently, etc... Pros rely on getting their hands on updated tech, and Apple has turned their backs on them on many occasions, since 2011
I could cite a lot more examples for #3, including the Mac Mini debacle since 2012. Wave #1 pushed me to the edge and #3 finally got me. Don't get me wrong, in the last 18 months I've purchased a used iMac for my son and a MBAir for the misses. But these are being treated as disposable machines, until my son is older and I can train the misses on Linux. Oh yeah, did I mention that also in the last 18 months, I setup a beautiful Ryzen system with a GTX 1080 that blows away the Mac Pro for $4k+ at about 1/3 the cost.
Apple has really lost it's way. And if someone like you, who detests anything NOT MacOS, is waffling, then that's a BIG problem.
