What I don't understand is why they limit what machines get this software. What is the point? I bought a tricked out Mac Pro and it doesn't come with this. I have an iSight so I *could* use it. I knew it didn't come with it so I'm not bitching about that, I just don't understand why they stratify it this way. How could it have any impact (good or bad) on their bottom line? They don't even sell the iSights anymore, right? Strange, if you ask me.
