FaceTime for Mac beta now available for download
FaceTime for Mac makes it possible to talk, smile, wave, and laugh with anyone on an iPhone 4, iPod touch, or Mac from your Mac over Wi-Fi. So you can catch up, hang out, joke around, and stay in touch with just a click. Sure, it’s great to hear a voice. But it’s even better to see the face that goes with it.
Grab it at http://www.apple.com/mac/facetime/ We're downloading now and testing it out, and when you do let us know how it works for you!
