Booking Through Thursday

All other things (like price and storage space) being equal, given a choice in a perfect world, would you rather have paperbacks in your library? Or hardcovers? And why?

At first I tought that I’d like my books to be in the format that they are mostly in now: paperbacks. However, what I’d really like is to have most of them in e-books and audiobooks. E-books would take lost less space and also would be easier on my back when I move next time. There are some books which I’d love to listen to but aren’t available in the audio format.
