The funny thing about being an indie author is what happens with the print book. The vast majority of my sales are electronic, and truthfully, creating a physical edition doesn't even offset the costs. But publishing the book (in the traditional sense) is something I've chosen to do, and I think it's something I'll continue to do for all my future books. For me, a book doesn't really feel done until I've got a copy in my hand that I can put up on my shelf. Only then do I have the physical evidence of the story I've spent so long trying to tell. Maybe print books are more for the authors than readers these days, but that's okay.
Books will always be books, whether made out of ink on paper or e-ink on a kindle.
