Agreed. We went digital-heavy with Pathfinder, all characters in HeroLab (there are so many modifiers in PF beyond a certain level you kinda welcome the help). But then everyone is staring at their screens all night.
With 5e we've gone back to paper sheets and it's way better. I still use a laptop to help DM but that's it.
That being said, projector gaming is amazing. What I really want, digitally speaking, from 5e is officially produced PDF versions of adventure modules. Pathfinder had this, which made it easy to extract the background graphic layers of maps (ie without text labels and notes all over it), since a properly authored PDF (ie as opposed to a scanned book) will have all this stuff on separate layers. If I want to do this in 5e I have to remove all the notes and stuff by hand in Photoshop which can be very time consuming.
