IM lovers can get the latest and greatest Windows Live Messenger 2009 at http://download.live.com/messenger. The video below explains the new features of Messener 2009. I personally find it simple and clean, features such as contacts profile updates, games and photo sharing (watch that in the video!) useful.
I’m still more keen to use Digsby as my main IM client since it allows me to login to any IM networks (MSN, YIM, ICQ, GTalk etc) but MSN Live Messenger 2009 really looks like a nice update and might get just more attention from now on.
