With the new Prestige Comfort Systems thermostat, Honeywell has introduced what it says is the world's first full-color, high-definition, touchscreen thermostat. It's part of the Prestige Comfort System that the manufacturer claims can cut your annual heating and cooling costs up to 33 percent by helping you better manage your heating and cooling system(s).

Honeywell claims this thermostat is completely intuitive—no owner's manual needed. The thermostat programs itself after you answer questions that appear on the screen, such as the time you wake up and when you hit the sack. A three-part Prestige Comfort system, which includes the Portable Comfort Control and the Wireless Outdoor Sensor, costs $200 to $700, installed, depending on the size of your home (price varies depending on the number of zones and thermostats installed).—Kimberly Janeway
