I live with my wife and two kids, and I'm the only one that cares about the size of the heat and electric bill. I know the lights are on because they've been left on every night since we've lived there, and if I don't walk around the house every night before bed and shut off the lights, they're still on in the morning.

I don't know a single person with kids that doesn't have to do this wonderful nighttime ritual - visit every room in the house and set the electronics to the correct setting. It's very simple and I believe a computer would do it better and faster.

I agree - all this automatic light dimming for movies and "scenes" seems like a gimmick. But I'd love to have a button on my phone that switched every light in my house off as if I had flipped a switch.
