Jim - I don't see any other laptops being able to run it
Either way, to me, a Mac is a bit of a toy. I don't actually need one... I have a PC which is the work horse, a MacBook would just be like having a weekend car - something just to play with and mess around on - hence why I can't justify spending the money they cost on one....
But I can see how much better in some applications they are than PC.... Plus, you try having the Mac Vs PC argument with Fastmaul, see how well you come off there
