You're completely right. My original comment wasn't really fair to the Nest alarm device. It clearly does have it's benefits, but not enough for me to overcome the potential issues with the device. I don't think the cost is that terrible, but I don't entirely trust its reliability and durability. A $100 smoke detector is fine if I don't have to worry about buying another smoke detector for a long time, but I don't trust the Nest to provide that longevity.
