Reading anything on digital devices has many physical, behavioral, and psychological limitations as well as advantages. At the very least, eye fatigue sets in even before the battery warning light starts scolding you.

Will you become a pasty white, reclusive figure forever lurking in the darker recesses of society in search of shadowy environs so you can catch, glare free, that illusive, perfectly crafted phrase? Digital readers are getting better at handling varied lighting conditions, but there are still challenges.
