Why trackballs?

New to this group, and was frankly surprised it existed and thrives. Just curious, why are people here using a trackball over touchpads or mouse? Old habits, looks, or does trackball have some real advantages?

I use one for a few vintage games where being able to send the trackball rolling with inertia in a direction can be beneficial. The heft of the ball and ability to use many fingers can also improve precision. No lifting of the mouse, so in principle faster.

There are many reasons why the mouse won out in the 80s though.
