Yes, digital textbooks can offer so much more, and yet maybe the "so much more" is their biggest pitfall: they (and/or the device serving as their platform) offer near limitless opportunities for distraction. While our attention span - or our lack thereof, trained as we are by the 3 second rule TV commercials push on us - might be able to get a major workout that leaves us exhausted and feeling like we have accomplished something (though in reality, hardly anything) - the digital format and form of delivery can rob us of our ability to freely focus. Let's face it, even with a good old-fashioned hard cover we can encounter distractions, and when we use digital, we're opening ourselves up to overwhelming levels of "opportunities for distraction" in which environment the human mind/body/condition is incapable of flourishing. Ironically, the very limitations of the physical textbook may be one of its liberating features.
