The Future of Landlines

An increasing number of people with both a cell phone and a home phone are choosing to junk their landline. In response, the makers of cordless phones are going on the offensive, making their phones look and feel more like cell phones--or even act like them.

"Many people in this industry are very, very worried," said Howard Gutowitz, founder of Eatoni Ergonomics, which makes software used to enter text into cordless phones.

With so much revenue at stake--the companies have become used to customers having multiple lines and are not interested in a trend toward fewer lines--cordless phone makers are going to keep adding features and keep making technology upgrades, industry observers say.

Already, some phone makers have added features such as games and directories, and they're dumping the traditional blocky design for a sleeker, hipper cell phone look. One British company has created a hybrid phone that uses cordless technology in the house, then jumps to a cellular network when it gets too far from the base unit.

"The test bed for innovation is going to be there; these phones are cheap, and you can justify the purchase because of these other functions, which are pretty damn interesting," Gutowitz said.

While only between 3 percent and 6 percent of all Americans have chosen to exclusively use cell phones, analysts say that number is likely to go as high as 10 percent. Aurica Yen, an analyst with The Yankee Group, said that means that in 2006, there will be as many long-distance calls made on cellular telephones as there are on home phones. Currently, the two totals are billions of minutes apart.
