The internet and globalization of markets and cheap shipping has taken a lot of the wonder away. It used to be a friend would go to Japan and come back with this absolutely futuristic walkman that simply wasn't available in the US market, and looked like nothing you had ever seen before. That's not really a thing anymore, and to the extent that it is (there are still products that aren't sold/marketed worldwide for various reasons), you can always just buy it on eBay or something.
What types of products would these be? Are they new categories of products, or variations of items that we currently have but work in a novel way? Examples would be ebikes before they were widely available, or electric cars that is more ebike material than car material.
