First of all, I think it is because the system's closure and ecology are very well constructed. iOS system has always been closed source, ensuring that all its system adaptations will be more perfect in hardware, and the ecological construction is also very good, you can achieve common in Apple's iPhone, mac and ipad products.

What do you think?
