I don't care what anyone else says, this is a genius idea. I cannot believe that nobody has ever thought of creating a smart smoke alarm like this before. I think many of us have been guilty of taking out our smoke alarm batteries when it goes off because you like your steaks well-done or burnt your toast because you had to pee. And I know a few people guilty of removing the batteries from smoke detectors because they're chirping that the battery needs to be replaced and can't be bothered to replace it, which is plain stupid and dangerous. The one issue with smoke detectors that Nest solves is not the annoyance of it going off during dinner, it's the annoyance of when you have multiple smoke detectors in close proximity and you can hear one of them chirping randomly that its battery needs replacing, but you don't know which one it is. You stand around like an idiot waiting for it to chirp again, but it's so random you get frustrated waiting and give up. The colour coding aspect of this product alone is something even generic cheap smoke detectors should integrate to better show when batteries need replacing. I think it would save lives.
