but I'm wondering what the actual useful applications might be.
Quite simple actually, they tell you when you need to start closing stuff. See my computers often get laggy because I'm doing many things at once and it's useful to know who the culprit is. Did I forget to shut down a tab with flash in it, or did something hang in the background and made everything crap. Often with two cores you'll get a hung app and not notice for a few days before you tax the other core enough to start problems.
