I think that both e book and paper book will continue to coexist during your lifetime. Trees can be grown. The materials to make devices or power electricity are going to be just as limited in 100 years. People who only occasionally read prefer paper books and since that group buys the majority of new books (due to their larger numbers), that is the group that will be catered to. Remember that the one study showed that the average reader only buys 12 books a year. Are the folks who read on the cell phones part of that 12 book a year group or the minority who read way more? That is what is going to drive it.
