I have been toying with the idea of listening to books in audio format for at least 3-4 years but only last year got seriously hooked on this. By now, I have listened to close to a hundred books this way and continue listening to them every single day. It has become a major part of my life. The tipping point came when I switched to iPhone and discovered Apple Books, which was extremely easy to use. Other than the ease of use, it is the wide selection of books that made this an attractive platform. But I do use other platforms, such as Libby and Audible as well.
