As the technology continuously develops, we find ways on how to make things convenient for us. We also modify things in order to provide us better and more improved benefits. In fact, evolution of physical books into an electronic book is just one example of this development. However, people have different feedbacks of this modification. Someway says that printed books are better and other would say the other way around. Readers, like any other consumer, want the best and the most convenient.
There may be a lot more differences, but still the value of reading is more important. Whatever materials we may use in reading, the ideas and thoughts that we have learned matters the most.
