Google has bought Nest Labs, the hot startup co-founded by the father of the original iPod, Tony Fadell, for a hefty $3.2 billion. Nest has been making forward-thinking gadgets for the home, like its popular thermostat, since 2011. The Nest Protect smoke detector was just announced in October of 2013.
Interestingly, Google has promised that Nest will remain its own distinct brand and operate under the leadership of Fadell.
