Damn this would have totally bitten me if they had ever bothered to enforce it. I am the guy that brings all the gadgets. Last year I brought my laptop, a tablet that I pretty much only use to watch movies on the airplane, and my steam deck (a portable gaming pc). And that's just the computers, I have other electronics in my carry on.
They could have made me pay for two of those. I was even searched at customs that time and they didn't bother me. They also didn't find my sudafed. I have bad luck at getting searched (about a 25% hit rate I think) but good luck on them never bothering me with anything.
For a past job I even used to travel to Cozumel with my work laptop too, 'just in case'. Fortunately with my current job I don't have to ever bring work with me. But I'll always be over their dumb limit just with my personal stuff. One more thing to add to the travel anxiety pile I guess. This law is kind of stupid in the 21st century.
