Cave drawings, smoke signals, letters, Pony Express, telegrams, phone calls, text messages. From the dawn of civilization, man has experimented with different modes of communication, each with pros and cons.

You might think that we've exhausted every variation on electronic communication - text, audio, video - but you'd be wrong. A new one is quietly winning over millions of gadget fans. They're free apps with names like Voxer, HeyTell and Zello, and they really do mess with the rules of the game.
Nobody's settled on a good name for this communications category. But if we call them voice-texting apps, or walkie-talkie apps, you'll get the idea.
They work on iPhones, iPads, iPod Touches, Android phones and Windows phones. You open the app, tap someone's name, hold down the big Talk button and speak. A second after you start talking - yes, even before you're finished - your voice bursts to life, extremely clearly, on your friend's phone, wherever it may be in the world.
Your buddy can respond to you by pressing his own Talk button, and the conversation is under way.
