I was right!
I knew it!
Google Talk launched last night whilst I slept (evening US time).
You can now download the client from talk.google.com
I had a very very quick play around with it before work this morning, you can bring up your Gmail contacts and add them to your contact list with the greatest of ease. (One click in-fact)
Also, it has the Gmail notifier feature built-in to it, kinda like the Hotmail notification that I lost from MSN years ago (due to not using a Hotmail account to logon) which is fantastico.
Possibly goodbye MSN for me..
