Apple holds back basic features until they "get it right." They could have had copy and paste in the first or second OS, but steve said they had not gotten it right. That's how they do things. It's not first to do it, it is first to do it right.
iChat is not an instant messaging software, it is a communication software with text, voice, and video. I suspect they are waiting until the chips and network are available so they can get it right. This might just mean having an iChat that does everything the desktop does, or, possibly, we will see a revolution of iChat on both platforms - think about the love child between Skype and iChat.
WTF is with phone numbers anyways. How archaic is it to identify someone by a number? Give me a name and let my computer, phone, etc ring. Google is working on it, you can't think apple has not realized it is not about phone, it is about data based communication whether text, voice, video or a combination thereof
