One advantage to physical books is their lack of sleep-altering screen time. The blue light from screens is supposedly bad for sleep patterns (Recent freakonomics podcast: http://freakonomics.com/2015/07/06/the-economics-of-sleep-pa... )

That being said I still am a supporter of digital technical books. The information goes out of date too quickly for a physical book to be useful. However, if you want to read Homer's The Iliad, it may be better to have a physical copy you can read before bed and retain on your shelves for easy access.
