Google Talk --- Yet Another Instant Messenger

The first impression after installing Google Talk messenger:
Asusual its the Google way, its very light weight application
with the simplest interface.

I made the yahoo msngr and GTalk side-by-side and Yahooo is
like fully armed ready to go for a war and GTalk is like
nude deprived of skin...! But the lite-wt interface is
certainly very appealing.
I found there was no option like Invisible.
There are other options like busy etc,..
It provides voice chatting as does yahoo and I m yet to play
with it.

Google certainly has a lot more in its cache to be released.
I guess the OS on the way...!
