“My favorite device is a Chromebook, without ChromeOS”
If you're sick of Chrome OS on your Chromebook, or can find a Chromebook for cheap somewhere but don't actually want to use Chrome OS, have you considered postmarketOS?
Since I was kind frustrated with ChromeOS, I decided to take a look at something that I knew supported my Lenovo Duet 3 for some time: postmarketOS. For those who don't know, postmarketOS is an Alpine Linux based-distro focused in replacing the original OS from old phones (generally running Android) with a true" Linux distro. They also seem to support some Chromebooks because of their unique architecture and, luckily, they support my device under the google-trogdor platform.

PostmarketOS is aimed at smartphones primarily, but supports other formfactors just fine as well. The Duet 3 is one of the tablet-like devices it supports, and it seems most things are working quite well. In fact, judging by the postmarketOS wiki, quite a few Chromebooks have good support, and with Chromebooks being cheap and dime-a-dozen on eBay and similar auction sites, it seems like a great way to get started with what is trying to become a true Linux for smartphones.
