One for the Museum

Cell phones these days are amazing. They can do just about anything you need them to: make a call, check your e-mail, surf the web, watch TV, and catch Pokemon. Back in the day, you needed a different device for every one of those functions.

An example: the alarm clock, an ancient relic that very few people use anymore. But before you had a phone with an alarm in it—a phone you keep by your bed so you can mindlessly scroll through Instagram before you sleep—you had to rely on these little guys to wake you up in the morning. And if the power went out at night and your alarm clock turned out, you were fresh out of luck.
