Hum, I think this is missing the main points. AirPods and Watches are gimmick. Nothing crazy innovative happened to the iPhones - apart the flatnessisation of iOS which in my opinion was a mistake - and Macs actually went backwards. The real Tim Cook test will be the ARM Macs. Can be game changing or it can’t sink Macs for good.
Gimmick or not, wearables (Watch + Airpods) are a massive business for Apple. Large enough that they would be a F500 company if spun out at current revenue numbers.
