Strikes me that with all of the more important things to be discussed -- such as whether it is better to have a child read to by a parent or by Siri (the voice) or whether it is better to invest money in teaching reading to infants or in buying them food -- the question of whether "real book" is appropriate or not when speaking of print versions is a waste of time, effort, and breath.
It is making the surface paramount over what lies beneath and draws away from consideration of what is truly important for what is truly unimportant.
