Nest, the company Google just bought for $3.2 billion, brings you the Nest Protect, a WiFi-enabled smoke and carbon monoxide detector that doesn’t annoy. A soothing voice warns you of danger and lets you silence false alarms with a calm hand-wave instead of a frantic towel swing – unless it’s an actual emergency, in which case it’ll rightfully annoy.
