I like the idea of reading eBooks, having tons of information in a small package like a Kindle or Sony Reader. Access to information, maps, dictionaries, and others would save time. In conjunction with a laptop, eBooks would enhance a writer's ability to work anyplace they desired.
The only current drawback is cost. I guess the concept is limited to the affluent or those with a large charge card "open to buy". As eBooks become more popular, costs will decrease, and will provoke competition!
Many eBooks are free. Project Gutenberg has almost 30,000 Public Domain books available, the "Classics! There are many other sites.
