Do you think the book is here to stay? Why or why not?
While the use of the physical book continues to evolve, I don't believe it will become fully extinct.
Compared to electronic sources, a physical book has many shortcomings. It's a closed source meaning you can't conveniently upload new information to the unit. A book is not connected to other information via hypertext. And, of course, the logistics of keeping a large volume of work in one place is prohibitive.
The eBook, and to a larger extent the internet, offer an encyclopedic approach to information offering the user a large volume of work in an open-ended, single-source. On page 81, Bolter describes the eBook by saying "Unlike a printed book, which can only contain one fixed text, the eBook is designed to be reloaded." It's an efficient asset for information applications and source citation as well as an application for entertainment.
Just as these pros and cons are listed as they are, for a fan of a physical book, they are opposite. Many people prefer that a book is a closed source offering a concrete beginning and end without distraction to other sources. The prohibitive sense of a library is also appealing as people wish to escape to a quiet place and temporarily "disconnect" from the world. There is currently a trend toward creating private libraries in new homes for this purpose. People like a place to escape with something more physical, less cyber. Ironically, there's a link to this story.
Personally, I like a combination of the two technologies. When I can, I read a physical book because I enjoy the tactile and visual sense of a printed text. However, when a printed text is unavailable or inconvenient (traveling, lack of light), I'm very glad I can still escape into a story via my iPod Touch with its downloaded books.
