Yeah, I tend to prefer on device resources when I can't have physical copies. Online resources tend to be a pain in the ass when you need them most, so I never think of them.

I don't play 5e, nor run a game with it, so I haven't bothered to find newer copies of the PDF. If they've changed that much in a few years that the official site/books are no longer useful for quickly checking things, I can't say I'll ever bother to look for new files. It would mean that they've turned d&d into a churn based monetary thing rather than a reliable game system. I'm just not interested in that.

I mean, I have all the old ad&d books, most of the 3.X, and the box sets from before 2e. The 5e stuff, I'll never buy any of if there's not a good reason to.
