I'm not a Mac user or a Linux user. I'm a Unix-like user, and pretty much everything else is gravy. Switching from iTerm2 to Tilix doesn't faze me; zsh still works the same. Literally the only apps I use that are Mac-constrained are Logic Pro X (I have a dedicated machine for that) and the occasional Adobe app--and I dual-boot my desktop and my primary laptop with Windows, so I care much less about that there, too.

Oh, and Keynote is nice, but web Keynote is fine for my purposes. But everything I use for my actual job is either a web app (LucidChart, etc.) or is eminently portable (Unix tools, VSCode, etc.).
