@ErikUden Hardcover books should come with a chip built in that contains the audio and digital versions of the book. I don't care if there is some sort of DRM that requires the book to be nearby for it to work. All I want is to have an included audio version that I own. In the 20 years since digital books have been popular I have probably bought two and maybe 10 audiobooks. I would buy so many more if I could actually own them.
