I only read fiction, so I always buy it pirate ebooks unless there’s a special edition of something that I am really excited about. I’ve bought all of Brandon Sanderson’s mystery novels in hardcover for example, and I buy the Stormlight books hardcover as well. I’d love to have the entire cosmere in hardcover, or better yet their special edition leather bound hardcovers (for the ones he’s done it with), but it’s just too expansive and expensive to justify.
In an ideal world, a physical copy includes a digital copy.
