Never underestimate the attraction of the paper book.
I publish a very long series of novels (comfortably more than a million words) on the Web. Clear HTML, totally free. A friend has kindly made downloadable files of the text in a variety of ebook formats. Again, totally free.
And what happens? In spite of the mind-boggling cost of the consumables required, people print it out! And email me all the time positively BEGGING for the opportunity to go into a bookshop and pay money for the thing in paperback. (Never going to happen, as neither I nor the author owns the rights to the characters.)
This mindset isn't going to change overnight. The on-line electronic text, given the chance, is an advertisement for the paper product, not a substitute.
