If you’re thinking about Linux and low on funds maybe your chromebook is supported by mrchromebox.tech/#home
I’ve been using it on a 2017 pixelbook with Fedora. No ragrets even after this thing turned me into a kernel contributor over audio regressions. I replaced ChromeOS on my partners as well. We decided to do it now since updates are ending relatively soon so she could go back while we look for a replacement, though she’s been relatively happy and I think what’s done is done now.
