video calling w/Yahoo Messenger
I would love a viable option for making iPhone > Mac calls via 3G (or even wi-fi), but i have a very difficult time trusting Yahoo to get this done. I feel as if Apple will roll this out in 4.2.x, a Snow Leopard update, or in a new iLife version.
Yahoo Messenger was garbage when it was only text. I shudder to think of how many holes and bugs a video chat application built by the same people would have.
We all know that the technology is there, but I'm not sure I want one of the first apps to capitalize on it. I'd rather wait for a quality, tested version from another big name.
