No. Book is something which we can keep and cherish forever. Laptops have just ruined the entire ideology of a book. We must remember. A PDF is not the same as a BOOK. Laptops can get you whatever book you want yes, but soon, the books you love and nobody else loves will start fading away from the internet. There won't be PDFs of them anymore. But you have the book. A book which you can keep with yourself, read it how many ever times you want without anyone stopping you. You get the sensation you get while holding a book which you don't get while reading from a laptop. And of course, from the laptops it can ruin your eyesight.
