The non android Kindle tablets run Linux with x11 and a heavily configured awesomewm. Most of the GUI is just java apps. The kernel and bootloader are downloadable from amazon and it’s very easy to replace the amazon stuff with a complete desktop environment containing xterm, Firefox ESR, gcc etc. Honestly even if they were more expensive the non android kindles are way better than most android tablets for anything except games.
