Lurking to see what folks think.. I have a really old nook which I rarely use anymore. Reasons for getting it was my ebooks are all in epub format, and I heard scary things about Amazon doing shady things with my books/data.
After setting up a home server, I now self host my books and haven't found an easy way of transferring books onto it, other than plugging it in with a cable. (Tried rooting it, kind of got it to work but it wasn't great).
I really miss being able to send any new epubs to it over WiFi/email/without needing a cable.
Now I usually read books on my phone, using Moon+ reader app and a WebDAV (LAN) connection to my server. Calibreweb is running to enable me to grab books when I'm travelling/away from home, but for long trips I'll sync the nook up with a cable. Battery life is incredible compared to a phone..
