Huh, #ChromeOSFlex is one wierd OS.
On the one hand, it uses MD3Y (so i can match the colors of the apps with my #googlepixel ), but on the other hand, the apps are all webapps, so there is no use.
The linux env is cool, one flag and i have igpu passthrough, and the apps has a theme similar to the Materia theme/style for GTK & Kvantum, but what's the use of using chromeos flex?
My MacBook Air 6,1 is certified and supported till end 2026, but uh, i can get infinite support with linux.
I was under the impression you can link your pixel and "chromebook" together and make use of the playstore, but no, it's only for real chromebooks.
Verdict: chromeos flex is good if you want a basic netbook experience.
