As others already hinted at, pretty much all the arguments against using the mouse for some things break down when you have a touchpad.

In most cases windows resizing, moving and usually selecting and scrolling (with chiral scrolling) are faster and more convenient by an order of magnitude.

And reaching out to a (central) touchpad takes about as much effort as reaching any keyboard key.

People should really give them a chance; unfortunately many are mislead by the Emacs and Vim's docs, but when they were written touchpads didn't even exist.
