I almost never see people using a left hand mouse these days.

As younger people start using computers they generally will learn with right-handed mice and will thus develop those fine motor skills in that hand. I wonder if this will make right-handedness even more dominant.

As a lefty I never had any problems adapting to a right hand mouse and actually find the keyboard to be better suited as a "left hand" activity and would have a hard time switching it up.

I'm a lefty, but always mouse on my right (keyboard left). This has made me exceptionally good at using hotkeys, to the point where a friend at a LAN party called me a hot-key whore. He wasn't (and still isn't) wrong. After using any program for a while, I will figure them out, including how many times to press tab to get to a field.

Living with laptops with touchpads for a couple of decades as a righty, I can use a touchpad perfectly fine with either hand, but a mouse is still right handed for me.

I mouse right-handed because it’s convenient, but I still naturally default to doing any novel task left-handed. It’s not a matter of fine motor skills, you can learn to do anything with either hand if you decide to, it’s just an unconscious preference.

I have switched between left and right mouse every few years when I was younger, just to see what works best for me. I could adapt to both, even though I can only write and draw with my left hand. I have settled with left-hand mouse because I feel like I can be a bit more precise for graphical works and shooters.

With the trackpad on my Laptop, I switch quite frequently and haven’t yet noticed any difference in precision. The movement is very different than mouse or pen control though and comes more from individual/multiple fingers instead of the whole hand or arm, so I guess that explains it.

With modern controllers the main joystick/thumbstick is on the left side. People are using both hands for fine control in different circumstances.

Keyboard is also both hands equally used. With handwriting less common, I wonder if people are shifting mostly towards using both hands equally now.

At one point I used to have two mice plugged in and would use either one depending on which hand was free.

I used right all the time. Got RSI. Now I use left at work all day, and right at home when gaming.

At work, I don't use a left handed mouse. Just those cheaper but common symmetrical ones. And I don't bother changing handedness. I just pick up the mouse and put it to the left of the keyboard.

shrug It works.
