Next Month: Emacs is my new operating system.

Well, if by "operating system" you mean "the layer of the computer that runs my applications" then I'm already there. ;) EXWM + Gnus + misc. other Emacs-based apps FTW.

In all seriousness though, I've used two different machines and three different distros with my current setup on top and it all feels the same. I didn't even notice in my daily interactions with the system.
