Re: kindle or android tablet, for mom? Whatever you use, see if you can back up the books. Amazon has been known to delete books.
I forget if it was B&N or Amazon, but they started purging books from users who didn't have a current credit card.
It was B&N -
I get books from elsewhere on an Android tablet. Back them up on a computer. Anyone tries to delete, I still have book. I won't use either B&N, Amazon or Google books.
