I personally like all of them for different reasons. I prefer to use paperbacks for everyday reading, but I like to get a copy of my favorite books in the hardback. Sometimes it just depends on the book, in the bookstore one or the other will speak to me, I would say I’m 70/30 (paperback/hardback) roughly. I will say one of my many quirks is that if I start a series with a hard/paperback, I have to finish them all the same! As far as e-books, they are convenient now and then, but I don’t think I will ever fully convert. I think that audiobooks are great for car-rides!
