I've been using Arch/Fedora with i3 and us-intl keyboard layout (plus xmodmap customizations).

After 5+ months, the shortcut (involving control/option/command instead of ctrl/alt) and keyboard layout (for characters like äöüß»«) still drives me crazy. Daily. It's super hard to re-train your muscle memory regarding complex shortcuts from IDEs such as VS Code and IntelliJ. I've found myself to rather use the mouse for certain tasks because I cannot recall the correct shortcut.

In those 5 months, I've probably installed 5 macOS upgrades each requiring >6GB download and >30min installation time.

Besides that, I'm very happy with the hardware: overall quality, great touchpad, great performance, no fan in the MacBook Air.
