The ease of audio books

I have never heard of Audio Books until I saw DB bought them for his listening pleasure.  He started buying them when he worked at his last company as it helped him past the time.  He said these books are great because instead of reading you are only listening to it and for him, he “gets” it better than reading.  Booksonboard.com is a site where you can get all sorts of books whether it be ebooks or audio books.  It is great if I can get my school text books from booksonboard.com.  Moreover, I can listen to it anytime and anywhere at my convenience.
