I’d been doing some retro-mac’ing the past couple days, and one thing I noticed is how impossibly “tight” the mouse cursor movement always seems to the physical input. It’s probably just a few dozen instructions from taking the interrupt to scaling and placing the cursor for the next vbl task, but it’s like sticking a 10 point landing.

Cursors on sun workstations (not just because of their optical grips mousepad) or windows boxes always felt like “oh there’s an abstraction between the physical hardware and the pointer, that’s just the way it is” - and nobody cared to make it better.
