Holiday gift guide offers something (sometimes off the beaten path) for all

The Nest Learning Thermostat is sure to be a hot — or cool — little number as it pays attention to how you heat your house and learns to adjust itself to your comfort zone. Made by Nest Labs, it is reportedly compatible with 95 percent of low-voltage air conditioning and heating systems and looks nice, too. It's also available online or at a home improvement store near you for about $249.
