I'm a book fan, so a kindle isn't really worth the money for me. I only buy non-fiction fitness books for my iphone if I'm impatient and want to be able to look things up on the go / recipe books that aren't particularly shelf-pretty (because then it's easy when doing my food shop!). For proper reading, I don't think I'd ever be happy with a kindle because I'm an aesthete when it come to books, I like the feel and appearance of them and pick my classics based on publisher / appearance of book - I used to have my books sent to the reading room that had the most beautiful books at university - even if they were totally unrelated to what I was reading! That said, my friends who have kindles LOVE them! But it really depends on you
