Everything I have that can be, is on a dimmer circuit. There are several incandescent that I've not replaced in years.
Dimmers have been around forever, people are just lazy.
I prefer the light (reveals are nice), and ability to dim is key.

I expect I will use LED's elsewhere, as soon as the price drops. They seem to make sense.

I can't say how many times I've seen rooms full of computers, monitors, just cooking away with no one at the terminals.
Not to mention the people who go home and leave their screensavers blazing. Really guys? Because you like the spinning 3d cube that much? Just turn the d*a*m*n thing off already.

Now of course if you are trying to heat the building with them, that works too.

But hey, I never bought an SUV either, so what do I know? 30+mpg for 2+ decades, hundreds of thousands of miles.
Yes, you're welcome. Now, hands off my *(&@^&$$*&%@ light bulbs!
