While primarily a note taking device, it can display PDFs and EPUBs. It runs Linux and has strong privacy features, though it's not dedicated to reading.
It’s not for me. My wife wants to read some manga and I think one of the apps she uses is only on android and other only on App Store. She currently reads on the web but it’s a poor experience according to her.
hmmm, Have you tried installing ReadEra?
I didn't understand, If she using an Android Tablet? If so ReadEra does a very good job
She doesn’t have a tablet, reading from web or Apple App Store app. But wants a tablet and I noticed both of the places she reads from have an android app. Otherwise she had to read from web which I think is not as nice as the apps - or so she tells me.
