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.
My kobo (10+ years old) has an browse option. Tried it, it kinda works but it’s kinda slow. An e reader isn’t built for browsing, e-ink is perfect for reading but slow for everything else. So I use my phone for browsing and my e-reader for reading. Since wifi is practically always off and it has e-ink display, the battery lifetime is staggering. That’s how I want my e-reader to be.
