The local news had a story on backpacks being too heavy for students nowadays. When I went to their website to reference the story I couldn't find it, but I DID find that they had in fact covered it several times before: 8/17/04, 8/23/02, I can go on, but I won't.
In a society where we stress more and more learning we seem to be putting more than just emotional weight on our students' shoulders, and apparently we've known about it for years. Think about how much an iBook weighs compared to all the books that it could replace. (And when you figure that e-books are cheaper and updated more often, those laptops can be very cost effective.) If there ever was a just reasoning for using digital media over printed texts, this is it!
