One thing you need to consider; if you are going to use a laptop is I/O speed. I realize that focus of this thread has mostly talked about screen quality (which is very important for photo editing) but if you end up with a unit with slow disks it will not be a pleasure to use. I'm not sure if the Mac Pro has good disk i/o (I know the mac airbook ssd tested out very fast compared with (for example) the asus zen book; but if the pro perform in the same vein as the airbook then that would be the unit I would recommend. While I am personally am very anti-apple (and apple software) I will admit they make solid hardware and have exceptional support (for example the zen book which has exceptional display - I would be a bit leary given some of the reviews with regards to fragility and while Asus is not a bad company for support it simply is not in the same league as apple).
