After following the mac mini through its first two versions, I have a theory on the lack of a core image GPU. In a nutshell, I think Apple has every intention of using the lack of a core image GPU as a clear point of differentiation between its low end machine and the machine next on list, the iMac. Your normal everyday user off the street isn't going to know the mini lacks core image abilities or even what that phrase means. If you DO know what it means, the mac mini isn't being made with you in mind. I really think it's that simple. In other words, the mini will always be lacking in functionality that the other Macs posses. Currently this amounts to no more than a ripple effect, but with future versions of Mac OS, who knows? I certainly hope I'm wrong, but I wouldn't hold my breath.
