There is only 2 reasons why I even run GTalk:
1. I have friends that use it from GMail because they can't use anything else at work/school.
2. The built in GMail notifier.
But personally I think it's crude, buggy, and seriously lacking in many areas as a chat client. (not to mention that the taskbar button flashing drives me nuts!)
actually other programs are running well and after several re-installs. i've decided to configure Miranda for Google Talk, eventhough i had to forego the PC-to-PC phone..

There are many other better messenger applications/networks that can do voice chat.
AIM has had the ability to do it for many years.
Yahoo can do it too, as well as
MSN. And I think there are others.
The three I mentioned also support webcams.
And if you just want pc to pc phone, try
Skype or
Glophone. Both are free to use to call other members. They don't cost anything unless you are going to use them for calls between pc & land lines.
