Backlit Keyboards

Does anyone actually use the backlit keyboard on their Mac? Granted, I like that it makes me feel like I'm in Tron, but as a touch typist, I never actually need it. Even when I do need to look at the keyboard for the function keys, I find the screen is more than bright enough. Anyway, I hear a lot of people mention the backlit keyboard as a big plus for Macs and was just curious.
