Considering that miniature books have been a part of literary and publishing history since at least the 16th century, I doubt this modern rehash will drastically change reading any more than the existing four centuries of iterations.
That said, mini books with this horizontal orientation are a cute and maybe convenient idea for some people. Anything that removes barriers to reading paper books is great.
