There is a way to remove the DRM and burn the resulting MP3 to a data disc it takes about 20-30 mins for each book part(bout a 7hr segment) most books I've done so far are only two parts so 40-60 mins total. I usually let it run while I'm doing the housework or watching a movie, its not very difficult.
Usually however I just use my audible app on my phone it's pretty darn awesome
