First of all, they should be optimistic about the scientific research level of Apple. This is the most important thing, and it is also an important reason why Apple has been a leading enterprise in the mobile phone industry for so many years. I believe everyone understands that science and technology will always be the primary productive force, but to innovate, we need to pay constant attention to the process of scientific research.
In fact, Apple is doing really well in this respect. For the whole company, a large sum of money goes directly into scientific research every year. For a big company, it is difficult to make money from scientific research, because in the short term, scientific research is likely to get nothing, but in the long run, this is the only way to make the company stand firm. Apple's research and technical team is really strong, which is why so many people are optimistic about it.
Second, Apple's marketing strategy. You can see that every advertisement of Apple's mobile phone is excellent, but generally speaking, there are really few advertisements of Apple. It must be said that the success of Apple's marketing strategy also benefits from the huge hardware advantages of Apple's mobile phone, and the operating system is almost incomparable to Android. Whether it is the unified layout of internal accessories or the fashionable design, everyone can't put it down, so together, these two points are the reasons why many big companies are optimistic about Apple.
