I don't understand what's wrong with multitasking in this context. It is really easy to listen to an audiobook while doing some light cleaning or during commute. I love reading and I'm trying to increase my paperback collection but I think everyone should at least give it a shot, my recommendation would be Stephen Fry reading Harry Potter - it's an awesome experience.
