My kids all have an e reader o' some kind. I bought DH the biggest Kindle out there last year. I wanted him ta be able ta git the font as large as he can. #2 DSon "buys" all the free books he can git his hands on. Those are classics. Some o' those are not programed well & eventually he will either buy a better on for the Kindle or go ta the bookstore. Some o' the "bad" ones he decides that he doesn't really like the story or content, so it was great that he got a sample before spendin' his $$. He loves philosophy & has been gittin' a lot o philosophy books that way. He actually is takin' philosophy this year. (Some days he drives me crazy discussin' it.) He balances it w/the bible. He says that if ya take it buy itself ya can git a slanted view.
Oops I got off on a rabbit trail.
