Since there were so many MBP owners effect by the Nvidia GPU problem, I think it would be wise to hold off on buying the new MB & MBP since Apple is using them, again.
Ho do you know they are using those cards again? Did I miss a story? By "them" do you mean nvidia? If so I would think that it would be better to buy from nvidia. Certainly they have learned thier lesson and at the very least fixed the problem.
