I use to feel that way about audio books to, but I became accustomed to them after trying a couple. The worst part is sometimes the narrator sucks and you either have to muscle past it or stop listening. I would imagine WORLD WAR Z makes a kickass audio book. Some titles just lend themselves to the audio format while others are almost impossible to keep up with. I got a Anne Rice book on tape one time and just could not follow along. God, she could dedicate 100 pages to describing a leaf on a tree.
