This could be the new cheaper Nest thermostat
One of the (many) obstacles to higher adoption of smart home technology is the expense. Back in March, Bloomberg reported that Nest was developing a sub-$200 smart thermostat. A recent tweet from Evan Blass, better known as @evleaks, may show the new device.
Bloomberg initially said that the cheaper Nest thermostat would drop the metal edges and contain lower-end parts to keep the costs low. The leaked image certainly seems to match that description, with what appears to be a plastic face.
The new model is expected to be released sometime next year. Personally, I'm not a huge fan of this design, but the finished product could end up looking a bit different.
