I have about 1400 Kindle books, all non-fiction except for a half dozen or so.
I’m not a fan of the format, and many of the books offered, but maybe if I ever buy a Kindle, I will get some use out of them.
We like that old books are available for very little money, or even free. Books by Henty are about $20 each, my boys got the entire collection (dozens of books) for I think $1.50. My daughter got the entire Elsie Dinsmore series for free. The library doesn’t have these books available and they are by far better than any current childrens or young adult literature.
Reading an entire book off a screen is hard for me, but you can find better literature there than a book store or library.
