I didn't see any mention of how many times he has to pick up his mouse when it gets to the edge of the pad to get the mouse from one edge of the screen to the other.
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
I haven't seen anything I like quite as much for quickly finding the cursor as macos's "wiggle for giant cursor" feature.
