That's a false dichotomy. I'd rather have a physical keyboard and a physical mouse (or touchpad).

The "line up the two axis" thing is immaterial, and has no practical impact on actual productivity.

Minimal impact and no impact different.

“Line up the two axes” was kind of a silly way to put it, but the position you aim your cursor varies quite often, but where you type on a keyboard doesn’t.

You can develop muscle memory for the latter. It’s why hotkeys are so widely used.
