Fully switched to Kindle years ago. Don't think I've bought a paper back in over ten years. One strange thing about audio books is I don't retain them like a regular books. I can remember details about books I read 40 years ago but I've listened to few audio books the first time through and come across them again after a couple years and can't remember what they were even about.
Strange how things change. A hundred years from now no one will even know what a news paper is unless they see one in an old movie. And almost no one will know how to read something written in cursive.
