And then we will have the whole PowerPC "we've realised that being the loner in the corner is bad, so we're switching to a funky new applemactastic platform. (small print: re-buy everything! yay for profits!)" debacle.
Seriously, ARM chips are good. No need for integration. No doubt they'll find a bug in their firmware, as it would be, and then lock the jesusphone until you have the chips upgraded. For a small labour charge of £120. If you don't want samsung to make your POC, then use prefab ARM chips in your own mactarded production line!
