I did it, it was pretty easy to do although required disassembly of my chromebook to remove the firmware read-write screw for my model but I’ve had to replace the keyboard previously and clearly managed to lose that screw anyway.
It’s pretty fast/responsive and everything seems to work although I did have to remove chromium and install chrome in order to be able to sign in to the browser. Obviously it isn’t fully integrated into the Google ecosystem like chromiumOS is, it is just a straight linux distro optimised for chromebook after all. I’m gonna be keeping it for sure…
