The only thing I miss about my Mac is the hardware. To be more specific: I miss the trackpad. I just picked up a 2018 ThinkPad Carbon X1 (6th Generation) and the machine runs Linux very well. The battery life is around eight or nine hours, the HDR screen is very good, etc. But nothing can come close to the Mac trackpad!

I'm running Arch Linux, for what it's worth. My use of several Macs over the last few years was basically confined to a web browser, Mail.app, and Terminal, where I installed a handful of GNU userland tools from Homebrew and essentially used it as if it was a Linux machine. I never bought into the Apple ecosystem with Photos, iCloud, messaging, etc. My pictures and music are organized in directories and I use open-source applications like darktable and GIMP (pictures) and cantata and mpd (music) so I didn't have any lock-in there.

Caveat: I'm on the systems / devops side, not dev.
