I feel this. I think I’m right on the cusp of this divide, too. I spent about 10 years doing tabletop RPGs with no thought of “errata,” let alone regular updates, but these days I run maybe half my games from my tablet, largely because I like being able to run a search to find a rule.

That said, if I could be sure that a print copy was going to be the last word on a topic, I might be more inclined to always make sure I had the book at the table.
