Some of the older e-ink kindles are very easy to get a shell on and are just running a buildroot with X11. The downside is that storage is limited and the partition scheme the OS it ships with is nearly android levels of goofy (all user data has to go on a FAT.) I think I heard someone found an exploit on the most recent one. If the pinephone didn't exist that would be tempting (and it kind of still is, having a small portable Linux machine with a week of battery life was nice even if it could only hold 4Gb.)
