@fluidlogic I've recently been considering buying one of the boox ereaders. I heard they run android, and you can sideload the fdroid store, and get the koreader app from there.
Plus you've got the regular app store as well for stuff like kindle and (and this has been annoying me so much that I couldn't read this on my own e-reader) the comptia self-paced ereader.
And also you can get tachiyomi for manga and such as well.
