I too love physical books. I love holding them, collecting them, reading them, and having them visible in my home, because that also helps discovery by my visitors; who hasn't taken a look at someone else's book case and thought: "That book looks interesting"? You lose that if the books only exist on a harddisk or memory card.

But recently I've been digging through some reading material which partly exists in PDF, and partly in big physical books, and I'm going way faster through the PDFs than through the physical books, because I read the PDFs on a tablet that I always have with me, and the physical book is big enough that I really need to sit down explicitly to read it.
