Walkie-Talkie Phones Hit the Family Market

Push-to-talk technology (PTT), which requires no dial-up and is always "on," started as a way for blue-collar workers like security guards to communicate efficiently, reports the WSJ. But now, some wireless companies are targeting a broader consumer market for PTT services, hoping the feature will catch on with teens who want instant updates from friends and family members who want to stay in frequent touch with one another.

... But push-to-talk service has some major limitations that could affect its appeal to the mass market. The biggest of these: Unlike text messaging, users who buy the service from different carriers can't communicate with each other."
