Google sells the Motorola Mobility unit it bought in 2012 to Lenovo for $2.9 billion, almost $10 billion less than what they paid. Google walked away with a lot of patents. The company also shells out $3.2 billion in cash for connected device maker Nest Lab, to start a push into the home with internet-connected video cameras, thermostats and smoke detectors.
