Popular iOS-compatible smart thermostat Nest isn't designed to be replaced every couple of years like the smartphones it can interface with. This according to Nest founder Matt Rogers, who touted the device's design for longevity in a "Fireside Chat" Saturday at Engadget's Expand conference. Rogers also explained that his company's thermostat is causing significant disruption in the thermostat market, which is typically dominated by companies that don't focus on design and the consumer experience.
