I'd think if Apple were to make an acquisition it would very likely be not a supplementary product (as Google likes to make) but more likely a significant piece of their manufacturing and supply chain. Especially considering their ongoing quarrels with Samsung (who's a major supplier of chipsets). Think about this, what position would Apple be in if they purchased ARM? (after some research it would be more of a buyback)
