I prefer hardcover books for my personal collection. They just look soooo much better on the shelf. A bookcase full of tattered and worn paperbacks just isn't appealing to me. However, I do prefer paperbacks from time to time. For Example, I bought Under the Dome on the day it was released and the gargantuan size made it difficult to read for long periods of time and am really glad that I read The Stand(extended & revised edit.) in paperback, but my mission is to acquire the entire SK universe in hardcover.
