I was introduced to the world of Audibles a couple of years ago. And ever since, whenever in the car, on a train, a plane or any other transportation means, I retreat to my bookish bubble and start listening.
Let's be clear that, to me, listening to books does in no way replace reading real books. This would be impossible! The touch and the smell and the looks of a book in paper is simply a world on its own... and I still do indulge in listening to loud music - when alone in my car. No noise pollution to the outside world, that is sure.
Let's just agree that listening to books while doing an "automated" action like driving or sitting in a vehicle is a good use of the time and a way to disregard erratic traffic happenings :)
