Well, not a full conversion. I still like to read paperbacks and hardbacks, because I love the feel of the pages and the smell of books. And I will probably never get an e-reader.
I always liked taking the bus when I lived in town, because I could sit there, listen to my iPod and read a book. Driving back and forth to work, you can't really read and drive at the same time (I've tried it; hasn't been productive because you can't focus on the book).
I never really thought I would enjoy audiobooks simply because you can't thumb through the pages, highlight or make notes, but it's better than listening to most of the drivel that comes out of the radio, whether it's music or talk. It has certainly made my drives home in traffic much more relaxing and enjoyable (much less road rage).
First one was
Post-American World by Fareed Zakaria. To be followed by
Aristotle and the Aardvark Go To Washington, The Return of History and the End of Dreams, The Forgotten Man, and now
The Gamble by Thomas Ricks.
