If e-mail is free on the Internet, why not phone calls?
It hasn't happened yet, unless you use computer-to-computer calling services such as Skype. But who wants to go through the inconvenience of talking on a computer all the time?
This month, however, two Internet phone devices are debuting that do away with monthly charges after you pay for the gizmo. And you use your own, traditional phone.
One of them, Ooma, uses a stylish piece of equipment and has at least the patina of coolness because actor-producer Ashton ("Punk'd") Kutcher holds the title of creative director with the company.
The other, MagicJack, is not as snazzy and has no celebrity endorsements. But the gadget is relatively small and a lot cheaper, at least initially.
Beyond differences in cost and hipness, each has pluses and minuses.
And there's is a third product, PhoneGnome, that's been on the market for more than a year. But it comes with such a big minus that it's useful only for a specific situation.
Here's a look at how these three Internet phone systems stack up.
But first, a caveat.
If you buy into one of these services, you're not just purchasing the equipment, you're also getting use of the company's network. And without the network, there's no service.
So what happens if the company goes out of business? Overnight, the device could become about as useful as a commemorative paperweight.
But why worry? Whoever heard of a tech start-up company failing?
MagicJack: This $40, pocket-size device is smaller and much lighter than a cellphone. On one end is a USB connector that plugs directly into the computer. On the other end is a regular phone jack where you plug in your phone.
And that's it. It's probably the simplest hookup in Internet telecommunications, and it works completely outside the regular phone grid.
When the computer is turned on for the first time with the device plugged in, MagicJack goes into setup mode and puts this message on the PC screen: "One minute of patience for a lifetime of savings."
Well, it's really closer to 10 minutes, but it's still relatively painless. You're asked to enter the address where you'll be using the device and then you're issued a phone number.
