Well, as an anecdote to why simplicity (at least in it's current form) is bad... All but one of my smoke detectors in my apartment are unplugged because they kept going off when I was cooking (would happen at least once a week). I was more likely to die or get injured from climbing onto a wobbly stool to turn off the 4 overly sensitive smoke detectors than I ever was in a fire. I am getting the feeling that this thread is split into two types of people, those who get a lot of false positives from their detectors and those who don't.
