Many a question’s being asked about what is a book. A real book. I think that’s a valid question, and also something that only can be answered from the right point of view.
A book always used to be something made of paper, with a cover around it, and words inside that smell of ink.
The digital revolution bestowed the e-book upon us, with a cover around it that looks like a little machine (e.g. e-reader, tablet or even a smartphone), and the smell of ink is absent for now (but wait for it, technology will catch up on that!).
So what is a book? Is it the medium that carries the story, the paper, the ink, the weight that comes with it? Or is it the story that’s conveyed, regardless of the medium it’s read from? Do you read a book or do you read a story? I think it’s fair to say that both options are true and real, and books are books, be they paper or e. As for the weight that comes with a book… e-readers have weight too and that can be a blessing for people who have problems holding up the big paper tomes.
There will always be paper books. There will always be e-books. And that’s the grand thing. Stories appear on both media, so you can take your pick. There is no absolute in what’s the best. The absolute could be your personal preference, and that’s not even a fixed point because there are people who appreciate a heavy, smelly book when they’re at home, but who take their e-reading device along when they travel (for instance when they don’t want to risk damaging the paper version).
The choice is yours.
