Readers who have started their reading experience through a book (and not through an eReader or through the Internet) will always stick to the physical book.
For one thing, the book is literally physical. You are holding the true key of power and education within your own hands, as you flip pages and look the words in the eye.
Secondly, nothing equals going to a library, sitting between millions of books on a wooden table with a hot cup of coffee next to you and a book that deeply interests you, nothing equals that feeling! Especially in the winter!
Writing and reading started with books, and they will always reside in books. After all, books are the things that started the Internet and eReaders and every little and single technology around nowadays.
For me, there will always be a big library of books in my house. No way I'm letting that amazing magic go away.
