That could be changing. According to gadget leak specialist Evan Blass, the device could be in for a whole new look. >Blass tweeted an image of the device, which shows off a whole new look. It retains its circular shape, but comes with a white ring and screen. While you can purchase a Nest thermostat with a white, copper, black, or silver ring, this looks to be a complete redesign: the traditional glass display looks to be replaced by a plastic one.
