GMail Video Chat
Video Chat is one of the important facility which was missing in Google. So far we would have used Skype or Yahoo for Video chatting.
Google now introduced Video Chat in GMail. Yes, this facility has been integrated with GMail and not with GTalk application.
You can install the video chat plugin to avail this feature. This plugin works in all major browsers. I have tested this in Firefox.
This will definitely be a threat to Skype. But still most of us will continue in Skype as it has more options than in Google Video Chat.
The following video demonstrates the GMail Video Chat usage.
