I listen to non-technical audiobooks during my walking part of my commuting - psychology, self-help, history and science fiction. I've also installed mobile apps for pluralsight(paid by my employer), udemy, udacity -- which allow me to download content and watch it in the subway; but I stil have to re-visit the course material and type things on my computer if I actually want to learn anything, otherwise its just more junk food for the brain. I don't think there are many text-only technical audiobooks, so if you actively drive that kind of sucks, because you can't watch videos, but then again, you're not missing much, I don't think there's anybody who aquired any technical skill by just listening to an audiobook.
