Phones

I find push-to-talk very annoying, especially when people use Nextel phones as walkie-talkies and I can hear the entire conversation all the way across the room.

In the highly competitive cellular marketplace, carriers are always on the lookout for an edge, a way to differentiate their services from their competitors’ offerings. Somewhat surprisingly, for more than a decade, Nextel has been able to use one enhanced service, Push-to-Talk (PTT), not only as a differentiator but also as a way to prop up its revenue and margins. That may soon change, however, as other carriers are now poised to deliver similar services.
