I would say no. Reading involves more use of one's imagination. Certainly, there are books that can easily put me to sleep after a few sentences. But when I'm reading my favorite genre (mysteries), my imagination is constantly at work. I cast the characters in my head using real-life actors and actresses, and a movie begins playing in my mind. That's the power of a good author.

If you'd say "no" to reading a book because it engages more use of one's imagination, how is reading a dead tree book different from reading an ebook on screen? The latter is still lumped together gaming and all other uses as "screen time."
