With a $3.2 billion hole to fill, Google's opened up yet another avenue for you to acquire Nest. The company's smart thermostat can now be had via Google Play, available for the standard retail price of $249. The Protect smoke detector is currently off the market following a bug that popped up earlier this month, so it's not available through Play, but the connected temp controller sure is, earning the top promo slot on Google's online store. Additionally, in celebration of Earth Day, Google's planting a tree for every Nest sold through Play today, so if going green is on the docket, it might just be time to pull out that wallet.
