Good morning,
I have an interesting situation in my church. I have a crazy-fast reader who loves devouring everything in my print library (and can write a summary to my toughest seminary books in a matter of just days!). I would like to get her access to my Logos library, so she can read through some of my other books and make notes, highlights, etc.
Only problem is that she's not technical. No computer, no tablet, no cell.
One family is willing to get her a tablet if I can work out the technical details (and persuade her to do this). I'm curious which is the easiest tablet or e-reader to use with the Logos mobile app (I figure that's the easiest way to go, as I could just download the books right to the app).
It would also need to work with PDF's, as I have a vast collection of such files that I would like to get into her hands as well.
I'd appreciate any insights. I happen to be quite technical, so I never had to worry about "what's the easiest". 
Thanks!
Brian
