Remember the Nest Learning Thermostat? The previously hard-to-find household gadget regulates the temperature of your home and sets up a pattern based on your usage, and even allows you to monitor and change the temperature of your home on the fly from anywhere by using your smartphone, tablet, or even a web browser. After being in short supply at launch, the Nest is now available at the Apple Store, which provides yet another avenue to get your hands on one. Lowe's also carries the Nest, if that's more convenient for you.
