But there is a downside to digital reading.

Many people complain of the harm electronic screens can do to their sight, while paper books are much friendlier to the eyes, and readers need to be charged periodically while you will never need to plug a book in before reading it.

Finally, for many readers, nothing can ever replace a book. The smell of a book, the feeling of a book, and the experience of a book can be never digitalized.
