It seems more than a little odd to us that Apple hasn't bothered to make FaceTime compatible with its own longstanding desktop video chat service, iChat, but we've at least supposed that it's an inevitability with whatever upcoming Mac OS X update or software bundle that Apple deems appropriate. Now Mac4Ever, who was spot on with a pile of rumors last year, but hasn't succeeded with its recent prediction of an iLife '11 launch in August, is saying that Apple is prepping FaceTime both for Mac and PC. We don't know if that means building a whole copy of iChat for Windows, or just making FaceTime compatible with some existing PC video chat service, but it would certainly improve the odds of us ever finding a legitimate use for FaceTime.
