Reading on screen versus reading on paper

I found a fascinating article in Scientific American titled "The Reading Brain in the Digital Age: The Science of Paper versus Screens" by Ferris Jabr. Jabr reports on several experiments conducted pitting reading on paper versus reading on screen for conprehension, and finds that people still tend to learn more and retain more from reading in print. But, as electronic versions of books and other sources improve and provide better visual cues, will this change?
