I'm all about physical books and the major issue I have with audiobooks is that if I fall asleep I have no idea when I was last awake. There are probably some programs out there that have a 10 minute timer where you have to tell the thing to carry on but there have been times in the past where I have fallen asleep and then woken up hours later and have no idea what was just read to me.

Physical books are the best for sure but not really an option for me over here in Vietnam. Therefore I Kindle almost everything I read.
