It will probably take a while, but home landlines could become as archaic as the rotary phone.
According to a Centers for Disease Control and Prevention study, more than one in five U.S. homes (22.7%) had cellphones — and no landlines — during the first half of 2009, up from 10.5% during the same period in 2006.
Ditching your home phone is easier now than it has been in the past, as cell phone companies compete for greater market share and alternatives to the home landline continue growing. For example, magicJack provides phone service when it's plugged into a computer's USB port and a home phone. It costs $39.95 and includes a one-year license for calls in the U.S. and Canada; after that, service costs $19.95 per year. (By contrast, Time Warner Cable's digital home phone service costs $39.95 per month.)
And, consider Skype, which is free when you communicate with other Skype users; this software application uses the Internet as a platform to make calls, hold video conferences and send instant messages.
