This in itself would not be a problem for me, if it weren't for the lack of competition. Mac OS is so far ahead in terms of "getting things done" and "just working" that it isn't even funny. And yes, I do know, I also regularly use Windows (10) and Linux (Ubuntu 16 LTS). I feel locked in: both "competing" platforms are huge time-wasters for me. I know some people feel different — past discussions have shown that most people do fewer things with their computers than me (for example, if all you need is a web browser, Ubuntu is a great choice).
Now that Apple is abandoning me as a customer (I'm not the mainstream), I feel squeezed: where do I go from here? What's even worse is that the cost of entry is now so high: developing an environment that works, and then convincing developers to embrace it is nearly impossible. And the only companies that have the resources to do it (Microsoft and Google) do it badly.
