I finally swapped mine for Super otw, being Android and also you don't need to pay a subscription to sync your computer and device through "the cloud".
replySuper doesn't yet come in color. I already have a B/W ereader that serves my needs.
replyTo be honest, I just need a decent ereader that supports Koreader. I definitely don't want to run apps, etc. I don't want to use it for note taking unless I can find a way to migrate the notes to my PC in my preferred format (which I may well be able to hack quickly with LLM support).
