What other ways does Apple make money besides mobile phones?

What did Apple earn besides hardware money? That's the money for buying software. A very important reason why fruit powder loves apples is the independent apple system and software. Apple's system utilization rate accounts for about 14% of the world. We know that downloading Apple software needs to go to Apple's special App Store. Needless to say, there are a lot of free software now, but there are still a lot of paid software. For each software that is charged, 30% of the fee you pay will be owned by Apple, which means that software developers can only get 70% at most. Just like highways, Apple builds platforms and collects tolls from software developers. There is a more crucial point. The software needs to be put on the shelves, and the paid software purchased by users will not be settled to the developer until three months later, which is equivalent to 70% of the money being used by Apple for three months for free, and it does not need to be returned. The money behind is also rolling in. How much money can Apple make with this money? Let's imagine for ourselves. Compared with the hardware money, this can only be regarded as "intermediate money".
