On the Notes of Retail, Apple had ~430 Stores in 2014, ~460 in 2015. As of end 2018 it is ~510, all the stores opened in 2015 were planned before Angela's arrival, so effectively she has slowed down the opening of new Apple Store under her tenure. During that time, Apple grew from ~800M Active Devices to 1.4B, that is 600M Devices increase, but less than 60 new Stores opened, if you are wondering why it is so crowed you cant even breath in Apple Store, that is why.
In 2015 I made a prediction that Apple could be aiming at 1B iPhone users by 2020. It seems crazy at the time, and a lot of people did call me so. But as of 2019 Apple has 900M iPhone users, so the 1B iPhone users doesn't seems to far off. I also thought Apple should be aiming at 1000 Apple Stores world wide. Apple Retail were growing at approximately 10+% before 2015, it was possible to reach ~750 by 2020, now not only have they not accelerated, they slowed down.
From reading all the latest Interview, it finally seems to me this luxury Apple idea didn't came from Angela herself. It came from Tim Cook ( or may be even Jonny Ive ), he wanted Apple to be more luxurious ( Apple Watch Gold Edition in 2016 ), and get Angela on board to try and help shaping the Retail part. Angela never wanted the job in the first place, but Tim Cook talked her into it. And one reason why her salary package were the highest in Apple.
I hope having Deirdre O'Brien meant Tim Cook gave up this idea of luxurious Apple. At least not luxurious in the normal sense, Apple is an affordable luxury in tech world, and that is drastically different to clothing or Jewelry industry. iPhone needs After sales services, and you cant rely on a small number of Apple store to provide adequate services to its customers and loyal users.
