One thing you didn't list is the video card. It is just important in making the selection. The Pro will give you a better video card, it is a faster computer and has more RAM. I think the choice comes down to how much you can afford, the Pro will give you more speed when your working your pictures.

But here is the real beauty of owning the Mac, all those other devices will integrate so well with it. You get an I Tv and you can sync all your entertainment on all your systems. It is an easy solution for the majority of your entertainment needs.

Personally I would go with the Pro, for me its all about speed.
