I installed Chrome OS Flex on my old laptop and I couldn't be happier, honestly. It has a really light and snappy shell, I can run all these PWA apps at once without so much as a hiccup, and I can use crostini to run Signal and VS Code. The only thing it doesn't handle is Steam, but I couldn't really play anything natively on that machine even on Windows.

And despite Linux being in a virtual machine the general experience is very seamless - I can install .deb packages by simply double clicking them in the file explorer!

Oh and most importantly, GeForce NOW works and I can still use it to play BG3 :D

(it goes without saying that the experience is much better if you're already tied to Google ecosystem, as the file explorer integrates, optionally, with Google Drive)

Wait, you can run crostini on ChromeOS Flex? I thought only real Chromebooks could do that.

You can run Linux VM on Flex. You cannot use the Play store and Android apps.

Could you get the Play Store working if installed on a generic ARM laptop?

Also worth noting that there is Chromium OS https://www.chromium.org/chromium-os/
