Google Talk has finally taken the last step in its evolution from being a minimalist IM client to a complete communications tool: video chats.
The Google Voice and Video Chat enables you to hold video-conferences with family and friends right on Gmail's interface, just like regular text chats. The video window appears on the right side and though you can't move it, there's always the option to pop it out and place it anywhere you like.
Google Voice and Video Chat has an astounding quality both in image and sound. Video streaming runs very smoothly and sound is just crisp clear. Besides there are no complicated configuration settings required, so you'll probably be able to have it set up and running in two minutes.
Being a Google Talk plug-in, you obviously need a Gmail account in order to use Google Voice and Video Chat. Also, your contacts need the plug-in too in order to be able to use video chats with them. Besides those two basic requirements, I can't honestly think of any other con about it.
Google Talk has finally added the one featured it lacked: high-quality, responsive video chats!
