Here's some interesting news. It appears that FaceTime will gain AirPlay support with iOS 5. Rene Ritchie at TiPb has posted a screenshot of a FaceTime call up on a big TV. Noting that he "snuck out to a developer friend's place to try it out," Rene calls the experience "magical."
This feature is available in iOS 5 beta 3, but as Rene correctly points out, not all beta features make it to the final product. If it does, however, millions of people will benefit, and my childhood dream of owning a Jetsons phone will finally be realized.
