This design seems to cement the trend at Apple to position their products as consumer appliances, not platforms useful for development.
The problem is, there's nothing else out there. Everything is going to shit in one way or another. Windows is now a disaster, Linux was always a disaster in terms of user experience and isn't improving.
Mac OS was the last bastion of somewhat good, thoughtful design, user experience and attention to detail and now they've gone to shit too.
Curious: what have you tried? People who use "Linux" as a catch-all in terms of UX usually have only tried a single distribution with a single desktop environment.
Yup. You've just described a disaster. How many permutations of <hundreds of distros> x <dozens of DMs> must a user try before finding a good UX?
Because there are at least four BSDs, Mac therefore isn't good.
Do you see how ridiculous applying that logic to any operating system is?
Linux isn't a disaster. It's a kernel. There are Linux distributions with great user interfaces and great UX, developed by people who are great at it. There are also distributions that aren't.
