In case you’ve been living under a rock for the past week or so, Apple has released FaceTime for OS X in the Mac App Store. The app will allow users to take advantage of the ‘built-in FaceTime HD camera’ or any other iSight-equipped Intel Mac, to bring you Mac-to-Mac, Mac-to-iPhone 4 or Mac-to-latest generation iPod touch video calling. This FaceTime video calling is only available if both users are using Wi-Fi. 720p video is supported and FaceTime will even ring on your Mac when not running once installed and will ring on any number of Macs all using the same Apple ID, ensuring that you never miss a call. After being in beta for a while, FaceTime is finally available for its first release, so if you’re a fan f iChat or Skype, and you have friends with iPod Touch’s, iPhone 4’s or Macs, then definitely download the FaceTime app from the App Store for only $0.99!
