Hello~Google Talk

Rumor finally came into reality,today I got the Google IM,the interface is so clean,no advertisement and no useless features~~
Although called to be an instant messenger,Google Talk provided us with only a few features.But I was amazed that it support audio talks.When we can get a GTalk as strong as MSN Messenger~~
I am wondering that yet we've got the IM,will Google OS be far away?
