Some authors change over time which can be a good or bad depending on your outlook.
Readers also change, I remember hating to be told that I HAD to read something back in school. Nothing chased me away from a book faster.
I'm not sure I would have gone the e-book route on my own but a friend bought me a Kindle, now I use it all the time and fully 50% of the fiction I read is on the Kindle.
One thing I like about the Kindle is all the books available for under a $1 or free. I now explore reading that before I would have not bought and if it not my thing I don't feel guilty hitting the delete button. So much easier than going to the library and now our local library has books for the Kindle online.
Thanks for starting this thread, it's always fun to talk about books.
