Update: It's been officially announced. Tens of millions of Mac users can now connect to iPhone and iPod Touch users. Facetime for the desktop includes everything you would expect including connection to mobile devices. This is going to rock! Nothing to set up, nothing to configure. Beta release will be out today at Apple.com.
It's still early in the Apple event, and nothing has been officially announced, but there it is, clear as day. There's a Facetime icon in the dock of the demo Mac being used to demo iLife 11.
Boom, indeed. More details when they actually get announced.
