If your house is less than 20 years old, you probably have a programmable thermostat. It's probably a plain rectangle with a handful of buttons and a monochrome LCD screen, and it's probably a slight nuisance to program. It also probably isn't connected to your home Wi-Fi network. Nest is trying to change that with its new Nest Learning Thermostat.
The thermostat is a round metal dial with a circular color LCD screen that works a lot like an iPod classic click wheel. That could be because Nest was co-founded by former Apple employee Tony Fadell, one of the creators of the iPod. You can turn the temperature up or down by twisting the dial, or you can go through its menus by pressing it in like a button. It can be set to automatically change the temperature based on the time and whether you're present.
