Apple briefly announced that FaceTime would be coming to Mac today. FaceTime is a video calling feature introduced back in June as part of the iPhone 4. It was then later added to September's refresh of the iPod Touch and will now be a feature on every new Mac and existing Macs as well with a free download. This means that users with an iPhone 4 will be available to video call people with a Mac as well as the latest iPod Touch. FaceTime goes into beta today.
