You seem like a reasonable dude, so I will bite on service revenue (Item No. 3):
[First, I have no
direct dog on this fight, like others in here vested heart and soul on AAPL, as all my investments are focused on Vanguard index funds: I believe in the US economy at large.]
Lets go to the Apple "services tape"/s:
- OS-independent Internet Services::= AppleMusic, iTunes
- Hardware-dependent Services ::= AppleCare[insurance], ApplePay[mobile payments], iCloud[storage], AppStore[Mac and iPhone Apps]
Have I missed one or more?
Note that the "big-boy" services revenue are proportional to hardware sales: Specifically, AppleCare, ApplePay, iCloud and AppStore.
Only when, and if, Cook can unleash a profitable services stream, independent and agnostic across player hardware, then one can state, irrevocably, that Apple has turned into a "pure services" company.
Maybe it will be AppleStream[TV and Movies], but until then, services revenue will remain proportional to iPhone, iPad, and Mac sales. [HomePod notwithstanding].
Just my view. [You probably feel otherwise.]
