As someone who currently has his physical books stored away in a locker a third of a world away, I'm souring to my former preference for physical books.
It's definitely not perfect but I wish more books went the DVD model where if you buy the physical disk version, you can also get a digital license. Without really having to buy both separately.
I'd love to have to have access to the contents of my books regardless where they are, while still enjoying them physically when I can.
Unfortunately the current electronic versions are buried in DRM and sold merely as limited licenses to the content.
