Repeating-characters in Lion

My UX senses are tingling all over! I have just uncovered a crazy ninja feature in OSX Lion and I needed to share it with the world. Go to an input text field or a textarea - any one will suffice (even your address bar). Try pressing and holding a key on your keyboard. What happens? Well, depending on which key you held down, it'll be different. For the majority of them, Apple has secretly killed off fat-finger syndrome by not allowing you to enter repeat characters without lifting your finger and pressing again. From now on, if something is over 9000, that's four individual keystrokes...

Letters that still allow you to press/hold: e, y, i, o, a, s, l, z, c, n. In addition, all symbols (tilda, comma, etc.) still allow you to press/hold. The other letters (and all numbers) are one-and-done. Apple, you crazy.
