I definitely prefer a book. I have some digital books on my Kindle, but I really only read them when I am away somewhere, or in hospital, which has happened a fair few times over the last few years. But nothing beats picking up a book, reading the covers, looking at the fly leaves, reading the list of other publications by that author or that published, than turning the pages to page one of the story. Somehow it is not as satisfying to try to do all that on a Kindle.
