Author here: I use a Logitech G Pro X Superlight but also I use the i3 window manager and rely on keyboard shortcuts for a lot of the navigation. I have the mouse sensitivity set so that the cursor can traverse the width of the screen when moving the mouse about 13 cm, without any acceleration. This is still precise enough that I can move the mouse pixel by pixel if needed.

I find it annoying that they've kind of got rid of mouse, tails and other easy ways of finding the mice pointer.

That's one of the main drawbacks of a massive screen is if you lose the pointer it takes a lot longer to find it. It's not a linear scale based on the width of the monitor. It's with the square.

So 50-in monitor is going to be about four times longer to find a mouse pointer than a 30-in one.

I don't like those hotkeys where you know it highlights it. I like the the mouse tail. That's the one that I can most easily find it. But generally those came out of fashion about 15 years ago

Pointer trails are still a feature in windows last I checked, and hitting ctrl to animate a circle around it works pretty much everywhere. I don't use either of these features nowadays, and usually find my cursor by moving it until I get to somewhere with high contrast.

I haven't seen anything I like quite as much for quickly finding the cursor as macos's "wiggle for giant cursor" feature.

Just switch to a neon pink pointer and make it larger. Problem solved.

Who needs a pad? And who needs the mouse to move more than 2 to 3 cm max, with dynamic acceleration? I'm just doin' 0.5cm twitches most of the times.

That's easily solved with mouse sensitivity settings, it doesn't matter the size of the screen if you set it properly.

With all that text, I'm hoping their religion is keyboard shortcuts.

i3/sway was recommended in the post, so yes.

Maybe they use a marble mouse or something like that.
