Creators of Kazaa came out with free application for making free phone calls using internet connection. http://www.skype.com/ But iChat AV pretty much does what Skype offers. And iChat AV adds video capability. Skype does have some advantages, cheaper price and lower bandwidth requirement. Anyway, my question is why is traditional voice only, phone service, still being pursued? How long will it take for iChat AV like service to completely replace phones? Would that ever happen?
