Google bought Nest Labs because it was an easy deal to do. Nest has started selling its products and systems at Home Depot, and Google obviously plans to integrate things far beyond its thermostat and smoke/CO detection systems.

Does the value of these rise if Google bought the VC-backed Nest for a whopping $3.2 billion? In relative terms, yes. Will these be the next buyouts from Google peers? That remains to be seen.
