Audio books have been discussed a bit before, but I never saw a list of recommendations. What books are good in an audio format (especially ones that can be listened to while driving)? I commute 45 minutes a day and would like to put that time to good use.
ETA: I'm mostly interested in non-fiction (goal here is to learn useful stuff, as opposed to entertainment).
I know you said non-fiction, but the Discworld novels, especially those narrated by Stephen Briggs, are really quite good.
