Does anyone here have one of these framework chromebooks https://frame.work/products/laptop-chromebook-12-gen-intel? Haven't seen many impressions on it so I've been hesitant to buy one. But it looks pretty good spec wise.
Framework and chromeos feel like a very strange combination to me.
Hard disagree from me. I've had a lot of Chromebooks and 3 frameworks, and it's a terrific match IMHO. I do wish you could switch back and forth between Linux and Chromebook without replacing the main board, but even that is a great fit. As needs change, you have options. Chromebook is great for many users especially now that it runs Linux apps, and can even be a very capable dev machine.
You need to swap out the mainboard to install Linux?
It's the other way around. If you want ChromeOS (in particular with its Verified Boot system for the OS image [1]), you need special hardware that comes with Chromebooks, including the Framework Chromebook. That has nothing to do with the ability to run Linux, though.

If you don't care about Verified Boot, you can install ChromeOS-Flex on a Framework Linux device (https://www.reddit.com/r/framework/comments/um0mk6/chromeos_...)

On the other hand, installing Linux on Chromebook hardware is straightforward.

The options are:

1. Use the Debian Linux VM (Crostini) that is already present on Chromebooks:

https://chromeos.dev/en/linux

All you do is click on a few buttons in the settings. This approach preserves Verified Boot.

If you want to replace ChromeOS on a Chromebook with a Linux distro, you can use Crouton: https://github.com/dnschneid/crouton

This approach removes verified boot.
