I always go to great lengths to check in for my flight in advance and have a paper boarding pass to show. Among other things, this avoids having to maneuver an app on an expensive, battery-powered device with carry-on bags in tow. And unlike my phone, if I drop it, ruin it, or lose it, it's no big deal.

FWIW, I also print out my hotel and transportation confirmations for my entire trip, but I consider my boarding pass to be far more important to print out than any of those.
