#4 Alarm Clocks
Alarm clocks are a thing of the past. In fact, clocks and watches in general are a thing of the past. Ask someone what time it is and their first reaction is to pull out a phone. Even better, smartphones come equipped with built in alarm clocks, eliminating the need for any other clock. There are even fancy alarm clock add-ons that allow music to be played as wake-up sound and since smartphones are already in the bedroom, why not use it as a wake-up device too?
