Apple will shortly extend FaceTime to desktop and laptop Macs according to Fortune.

Introduced with the iPhone 4, and now available on the new iPod touch unveiled earlier this month, FaceTime currently offers face-to-face video calling over Wi-Fi.

Fortune highlighted a story on French site Mac4Ever, which claims Apple with extend FaceTime not just to the next gen iPad, as recent rumours suggest, but to all Macs.

The report claims Apple are planning to ship a FaceTime version of iChat that would allow anyone on a Mac to chat with other Mac, iPhone and iPod touch users, and eventually iPad users.

Currently, the iPhone 4 and new iPod touch, comes with two built-in cameras, one on the front above the display and one on the back. According to Apple, the front camera has been fine tuned for FaceTime, offering the right field of view and focal length to focus on your face at arm’s length.

Fortune estimates as a result, Apple could ship as many as 48m FaceTime compatible devices this calendar year.
