That is really an indictment of the sorry state of PC trackpads. When I use my partner's MacBook with its pixel-perfect, glass trackpad, I never feel wanting a touchscreen.
Sure, i actually have one (well, kinda, i have a GPD Win which has a touch screen although i still prefer to use the joystick to move the mouse even if it s a bit slower) but optimizing the UI for the rare case doesn't make much sense to me.
