My wife and I both have NextBook Android tablets that we use for reading and Internet access, among other uses. I prefer Android so I can run the same apps on my smartphone. Our e-reader app of choice, for instance, is Moon+ Reader Pro, and we download mostly free or low cost books from Amazon and other sources, including our library service. I use a program on my laptop (Calibre) to convert book formats as needed, and then automatically send them to the tablets using DropBox. Moon+ Reader's DropBox support also automatically synchronizes my current reading position on the tablet with my phone, and vice-versa. Very handy...
