Im trying to help a friend without having in depht knowledge.
She wants an e book reader (phone is suboptimal) that is not limited to a company and at best supports tumblr which needs a browser like waterfox or an app (i will try to reccomend her wafrn later on)
most foss e book readers i found are a minimalistic linux system that seem to purely support e books
It simply being an e book reader is probably fine but bonus is bonus
Edit: thanks for all the useful answers, i will talk with my friend further about it but i didnt want to bloat the comment section as every comment is very much appreciated.
Your friend would better be served by an Android-based e-book reader. Kobos are low-powered and their browser very limited, I’m not even sure tumblr would work.
My father has a Boox, it runs straight android. I put f-droid on it, taught him how to use Anna’s archive and he loves it.
Boox are solid devices. We’ve got two at home and love them for reading. Web browsing static pages/images is fine, but video kinda sucks given the refresh rate of e-ink.
