The classic disruption story is clearly important here as is the pattern of recent failings by Intel. There have been other factors though that contribute to a more complex story: - The availability of third party IP (Arm CPUs and originally Imagination GPUs) and manufacturing (Samsung and TSMC) that have allowed Apple to pick and mix to build its own SoCs. - The fact that Arm has clearly been much more focused on power efficiency which might mean it has IP which Intel can't access (speculating here but we have big.LITTLE). - Possibly the most importantly, the the benefits that Apple gets from being able own the whole stack and design SoCs that precisely match its needs. As a result I'm a bit sceptical about whether Intel would have got Apple's mobile business long term given that market's eventual structure: the advantages of Apple's current approach are just too great.
