I still have an old three-button Logitech ADB trackball that I’d been using since... um... well, OS 7.something. I think I got it new sometime in the early 90s.
About the same for me. I had a Logitech “Millenium Falcon” looking trackball with my 386 PC in the early 1990s, and bought the same type trackball when I bought a Mac Performa in the mid 90s. I never did understand why Mac people were one-button people, and I never liked mice.
I use my PowerBook as a desktop most of the time, and have this same giant, silly split-key keyboard, wireless Logitech trackball, and flat screen monitor at home and office.
I’m not sure why it is that all the stuff I like seems to always be on the edge of extinction because no one else likes it. I can only conclude everyone else is weird. ;)
