My work machine is macOS as the company won't let us use Linux. My home machine is Arch Linux (obligatory "BTW") which I migrated to after Ubuntu dropped Unity and started forcing Snaps on everyone.
However, a nice shameless plug for my Terminal file manager: DF-SHOW which is designed to work on all Unix like systems.
As Lemmings was one of my favourite games growing up, that's also gets my vote.
I replaced mine with "sourcing map 2.5mm Ceramic Bearing Balls, ZrO2 Zirconium Oxide Ball G5 Precision". The difference is night and day.
I don't have much experience with other trackballs. I had a thumb control one from Logitech, which needed cleaning about as often. A small price to pay for pointing perfection, though.
Not sure yet, a lot of subs haven't set up on Lemmy yet. Hoping that'll change after the blackout next week.
