When I was having breakfast in the hotel this morning, a guy sitting at the next table had his laptop open and walked away from the table for a few minutes. I glanced over and was able to see his calendar details and it would have been real easy for me to change, delete or cancel something.
What is the etiquette here? Do I tell him not to leave it unlocked in a public place, or ...?

I think the etiquette is: Don't be a jerk. (kind of a baseline for etiquette)
This person felt safe. For a variety of reasons (including your default behavior being: don't mess with people, even if you know how to), it sounds like they were correct to feel safe in this instance.
Unless you have good reason to question this judgement (e.g. you personally successfully intervened to stop another person from taking advantage of them), I would encourage you to at least consider that the risk they took might be reasonable and/or mitigated in ways that were not obvious to you.
Also, consider that making that person feel unsafe may not help them in the short or long term. My ideal world is one where the default is that we feel safe, not the one where everyone is constantly on guard against everyone else. If someone manages to get there before me, that is a win that I want to figure out how to replicate, not a challenge to my choices.
In fairness, I'd like that feeling of safety to be grounded in reality, but it doesn't seem to me that making this person feel unsafe necessarily makes them safer.
