1. Physical books never run low on batteries.
2. Much more efficiently than with digital books, you can put your finger in your spot in a physical book, flip back and forth in it as needed, and then go right back to your spot.
3. You can put physical books in multiple places (desk, bedside, bathroom) to remind you to read more often. You lack that visual cue to read the digital books that are hidden in the hard drive of your iPad.
4. It’s faster to reference a book when all you have to do is pull it off the shelf and open it up.
5. Printed books ignite all your senses. I like the smell of a new book, and the texture of the pages’ edges under my thumb. I get more pleasure from a glance at the design of the cover before I open the book, compared to the immediate transport to where I left off in my Kindle app. And the thud of closing a book, after you’ve finished, it has a triumphant ring to it – one that the puny speaker of a mobile device can never reproduce.
6. Physical books are easier to loan, borrow, and give (especially in bulk).
7. Because the pagination changes based on your text size, it’s difficult to follow and contribute to a group discussion about a book if you are one of the few who read it in iBooks.
8. The ability to write in the margins provides much more freedom to develop your own note taking style.
9. It’s easier to keep track of your progress while reading a physical book.
10. The context of a digital book, since it consists of apps, makes a high level of focus difficult to achieve. It sucks away the attention you can give to what you are reading, even if you have the discipline not to check sports scores or email, because the other stuff on your device is in the back of your mind.Fonte: http://pastoralized.com/2012/02/10/10-reasons-why-physical-books-are-still-better-than-digital-books/
