When you and your contacts have each other in Circles, you'll be able to chat with them across Google properties such as Gmail, Google Plus, iGoogle, Orkut, and the Google Talk Client.
So your Google+ contacts will now be integrated very tightly with your Gmail and other contacts and you will be able to chat with them from whichever service you are in at the moment. Multiple interviews with folks at Google have said that Google+ was the path to further tie together the various Google services... and now we're seeing that in action.
