(Google Talk uploaded by brownpau.)
Google Talk, Google’s new instant messaging and voice chat service. Sadly, the Google client is Windows only, but Adium X on Mac OS X 10.2.8 is hooking up to Google’s Jabber server just fine, so I’ve at least been able to message other eager early adopters. (Screenshot is of my desktop, with a notice from “gmail.com” that talk.google.com is now working.)
Update – I agree with Darren Rowse: “It doesn’t add anything to my life as a Mac user.”
