There's a difference between E-books and audio books... I just wanted to make that clear.
There's just something about the actual book, especially old books (Love the smell of old books, mmmm) that just draws me in, they feel so regal and defined. Perhaps it's the fact that it's physical, and boy do I love me some full bookcases.
I read e-books too, those are great for when you're on a trip and can't hold 50 books in your bag.
