Why is Apple a great company?

Personally, I think Apple is not successful in China, let alone great. Just look at the market share of Apple phones and Nokia phones in China. As for Apple's success in other European and American regions, this is mainly due to the different consumption levels and living needs or pursuits. Apples are too picky. Look at Apple and Android. How nice that Android doesn't open source code! I believe that Android will definitely surpass Apple in the future. .
