Really? For example as a software dev using Linux as a daily driver (so no gaming), would I not need a mouse at all with a Mac? (considering buying one)
I didn't use a mouse since at least 2006. Before that I was mandated to use one by the company I was working for but I probably didn't. Why should I lose time to move my hand to grab the mouse when it's already close to the touchpad?
I connected a mouse a few times to play some casual game but I'm not playing games anymore on my laptop.
There's actually a few benefits, like touchpad gestures for app and workspace switching being much faster than the equivalent keyboard shortcuts.
