BTW, I don’t know what you had in mind for an external monitor, but I was just informed by matrox that the mxo does not work in mastering mode with the new MBP’s. It will only work in presentation mode. I cant tell the difference between presentation mode and just hooking my lcd directly to my MBP. I hope they are fixing this, as it was/is the only viable option for color accurate hd laptop monitoring that I am aware of.
