I couldn't help notice that in the Keynote, Steve said Apple would be shipping tens of millions of Face Time Devices this year. This is a bit weird as he used the word devices rather than iPhones which to me says there are more devices supporting Face Time to come. The obvious one is a Face Time app for Macs to replace or embellish iChat, which would seem ideal given the wifi-only nature of Face Time and prevelance of webcams in Macs. However, the way Face Time is currently invoked (during a phone call) seems to limit it to iPhones - especially as we were told there didn't need to be any "buddy lists".
