I'm actually surprised that they didnt have motorola making their chips given the long history they had with motorola up until implementing the Intel CPU's etc. With all the money they Apple has to invest, i am surprised that they arent working with motorola to come up with their own, however I can see shopping around for another chip manufacturer vs reinventing the wheel so to speak if another reliable chip maker is available and the cost is just the cost of the chip vs the large chunk of change into developing their own from scratch with motorola's help.
