This screenshot shows us that Google Talk support has been the latest build of iChat 4.0. Google Talk support is a welcome addition toiChat – and I hope we see more IM client support before the final release. I have several friends who use MSN Messenger, and even a few who use Yahoo Messenger as well, and it would be nice if I could just use iChat to talk with all of them.
Right now, that is what keeps me from using iChat as my primary chat client. I will always choose a client like Adium and Pidgin (formerly Gaim) as long as I can’t get full chat support in iChat.
