Already available for the iPhone 4and latest iPod touch, FaceTime will be making its debut for Mac OS X today.
Rather than being implemented into iChat as previously predicted, FaceTime is becoming its own standalone application where users can conduct phone calls via Address Book.
The video chat window can go full screen on your OS X-based laptop or desktop, and it will automatically toggle the window from portrait to landscape (and vice versa) depending on the device your counterpart is using.
Announced in Cupertino this morning, the beta version of FaceTime will start rolling out today.
