A friend of mine once said ...
"When I read, I like to feel the turn of the page, hear the the turn of the page and see the turn of the page"
When Pr'ing a physical book you are really engaging the kinesthetic, auditory and visual faculties ... a truly whole mind and body experience.
Computers really only engage the visual and nothing more ...
The more faculties you involve in the learning process the better.
Also, it's best to use your natural given tools ... you know, the stuff you came into this world equipped with.
Love and Light
