I play D&D in person using a paper character sheet and physical dice, but I created that sheet using D&D Beyond. And most of the rest of the party uses D&D Beyond on iPads.

Holy hell is that more convenient for tracking spells and subtle rule interactions than what I used to have to do as a kid.

In my eyes, it's letting technology do what it does best -- get details right -- and frees up slightly more casual players to do the fun roleplaying part without being so bogged down.
