You know how when you press a key on your keyboard and it's all mushy and there's no real way to tell when the key has been depressed enough to register? Well, these keyboards have an actual spring in the keys that buckles, so that there's resistance to a certain point and then it gives way with quite a click. It's as if the keyboard does more than simply lie there. Other than it being a little loud, it's a much more enjoyable experience to type on, at least for those of us that type a lot.
