Not even a Mac user and have been legitimately considering a move like this.
My desktop and Thinkpad run Gentoo. A NAS I have at home is the build host. I am a business software consultant, and a common thread in all of my interactions is: I need to be prepared. If I'm fiddling with "hang on my mic doesn't work" or "i need to reboot", I look silly.
An onsite visit might be in an executive board room, or a closet in the back of a warehouse with a TV from 2007 and a VGA connector.
If I need software installed quick, like Zoom or something, Flatpak gets me 95% there. Yes, I could use Ubuntu or something normal, but I like portage and long for the day I can use FreeBSD seriously on the desktop.
So enter Chromebooks, which come with portage, can use Flatpak, and the OS is basically just a web browser. Plus, I don't have to wrestle with SELinux, or any of the other nitty gritty stuff that gets in the way of real work™. It's either a PWA or an Android app, and it just works.
