Aside from reading books, I am also an avid podcast listener and I have been listening to several podcast genre's on my iPod. There's one podcast show for sci-fi/fantasy and book afficionado called "Sword and Laser"
The Sword and Laser is a science fiction and fantasy-themed book club and podcast, hosted by Veronica Belmont and Tom Merritt. The main goal of the club is to build a strong online community of sci-fi / fantasy buffs, and to discuss and enjoy books of both genres.
You can follow the show the the Sword and Laser website as well as subscribing on iTunes just search for "Sword and Laser"
