As much as that's true, Apple has been trying to dig deeper into "services" over the last decade.

As I inderstand it, Apple isn't organised that way. They have OS teams, app teams, design teams, which work on whichever product at a given time. They don't have product-specific teams. As for Apple being tiny without the iPhone; it's huge but Apple Watch (commonly described as a failure) is estimated to be a bigger business than Microsoft's Surface business.
Apple minus iPhone means no watch, no tablet, and marginal market share since these products help spur sales in the computer area. Using a MacBook as a hub for all your Apple devices is a compelling reason to get one.
Look at how hard it has been for Microsoft to grow market share being what is basically an OS company with no significant hardware sales to speak of.
