Before there were cell phones, text messages and instant messengers, there were landline phones some were even the rotary kind. But cellular phones changed all that. A February study by the Pew Research Center found that 41% of Millenials don't have landline phones as opposed to the 13% of baby boomers who are cell-phone only. The study also found that 83% of Millennials have slept with their cell phone either on or right next to their bed. Dependent much? Another side effect of the cell-phone age is that pay phones have all but disappeared, answering machines are a thing of the past, and "waiting by the phone" is just not done anymore. For most young folks, the only way they will own a landline phone is if cell reception is bad at home or if a cable triple-play package is more cost effective.
