Earlier quoted context omitted.
Yes, I touch the pad by accident all the time. But why is Apple so good at detecting which touches are accidental, while so many other manufacturers are not?
On Linux this works similarly. ~5 years ago my old laptops did the 'disable touchpad when typing' thing, now with libinput the touchpad has excellent and completely invisible (to the user) anti-false-touch functionality. Apple has invested the time to make great trackpad drivers. People have invested time to make libinput a great driver for Linux (in this regard - it does lack customization possible in older drivers)…
If touchpads are good now, then I might go dedicated Linux again when it's time to upgrade from my aging MBP.
