Touch-screen Macs is kind of a terrible development for anyone who loves the Mac. It's not just a harmless feature that you can ignore if you don't want it, because it's customer-facing and will now generate complaints and bugs from people who do use it. Those people will complain (rightly) that macOS UI widgets are too small to accurately manipulate with your fingers (they are indeed too small) and don't make sense with a touch screen (they don't make sense).

That means Apple will begin imposing all sorts of UI dreck on all of us, whether we want to use our screens as touch surfaces or not.

This is basically what happened with Microsoft - Windows Vista and 7 were installed in plenty of laptops with touchscreens, and customers would complain about not being able to maximize windows without closing them, not being able to open menus without touching toolbar buttons, etc.

Eventually Microsoft listened to them and we got Windows 8. Now this is the beginning of the same process for macOS.
