David Pogue: New York Times: Google Shakes It Up Again With Free Phone Calls: Google .. shook up Web searching and advertising. It shook up free, Web-based e-mail services .... shook up the way companies go public. .... Calls to American and Canadian phone numbers are free ..... Calls to other countries are very cheap ...... If you have a free Google Voice account too, then you can get incoming calls, too. ..... it’s increasingly clear that one day, the Internet, not the outrageous cellphone companies, will connect our calls. The ultimate, of course, would be free calls from a phone, to a phone ...... even closer to the “free calls from a phone, to a phone” ideal. Now it’s free calls “from a computer, to a phone.” .... What if Google released an app like that for Android phones, or the iPhone? .... for the first time in history, make unlimited free phone-to-phone calls.... It would completely change the game .... the Internet-as-phone-company paradise that almost certainly awaits us.Paying for phone calls was always ridiculous. And it still is. Now that we have computer to phone free calls, Google should go ahead and stop pretending, and I know it already has the technology. Get this ported to the smartphones, and we already have it.
The reason you should not call someone or not talk to them long is because you don't have time, not because you don't have money.
