That was epic lame. RGB to RGBY color space? How does that even work? Full yellow lights up 2/3rds of the sub-pixels on an RGB display, and human vision can't tell the difference. What does an extra Y channel gain? Technology for the sake of specs.
My home thermostats have always been located in high traffic hallways, because rooms tend to be along the outer walls of the home, and the thermostat is centrally located away from the outer walls. So Nest would light up anytime someone walked past it to the bathroom. How innovative. /s
