Microsoft has finally released Silverlight 4 desktop client for Facebook which was first demonstrated back in April, 2009. According to iThinkDiff blog, Microsoft released the app out of the blue without any announcement. Of all the facebook desktop clients we have tried so far, this one takes the prize.
It has a clean interface and looks much like the Zune desktop app. The best part is that it is actually usable and comes with build-in notifications(alerts). Navigating facebook with this app is seamless. The minimalist design, combined with easy-to-use functionalities makes it a killer desktop client and is a must-have for all facebook addicts out there.
Note: When installing the app, Silverlight 4 beta will be installed. Ofcourse you will have to allow permission to this app before it can connect to facebook.
It is available for both Windows(XP, Vista, & Win 7) and Mac.
Update: Below is the quick demonstration of the app on Tablet PC by iThinkDiff blog.
