Cellphone app developers are our heroes. Their whole purpose in life is to take one of the most useful devices ever manufactured and figure out a way to add functionality. They are the people who put power in our pockets.
Most people who live in the northern states know how uncomfortable it can be to get in and start a cold car. The seats are cold and stiff, the steering wheel is like a disk of ice, and the defroster is blowing air with a wind chill. Since the late 1990s many technically-adept (and cold-hating) northerners have managed to avoid the grim reality of “warming up the car” by installing remote starters in their vehicles. Being able to start your car from the warmth of your house or office with the push of a button eliminated what was, for some of us at least, the worst part of winter.
