Emacs is awesome, but it is unfortunate that on Windows it still only supports x64, which is a legacy platform at this point. Hopefully arm64 will be supported soon as well!
Emacs is a serious tool, you choose it first and only then prioritize on the OS. It's like complaining that editing videos with Adobe Premiere on Linux is not a very solid experience, or something like that. Well, if you're a pro video-editor and you must use Premiere, then maybe you need a non-Linux box to do that?
It's almost not even funny, but I tangle all my dotfiles from an org-mode file. The files it generates are all read-only - to discourage me from writing in them directly. This makes my OS config semi-immutable. Bootstrapping a system from scratch takes no longer than a few minutes and the biggest bottleneck is properly getting access to that dotfiles.org and installing Emacs. This has worked for years and that's why I never had to really learn Nix. I guess Emacs for me is the "true OS", and whatever on top is "just kernel stuff"
