Just a few months ago, FaceTime video chat was only available to iPhone 4 owners, and this happened only via a Wi-Fi network and nowhere else. Well, today Apple has decided that it is time FaceTime video chat is ready to be a Mac OS X application so that those sitting behind a Mac can engage in video chat conversations with one another, not to mention owners of the iPhone 4 and iPod touch as well. With more than 19 million FaceTime devices shipped worldwide to date, you can be sure there is at least one FaceTime conversation happening every single second of the day. Now in beta, we do hope that the final version will be finalized soon.
