I remember feeling the same way about Apple back in late 2012/early 2013. I was ready to replace my iPhone 4, and Apple was only making phones with small screens, while the market trend was for larger screens. Then Apple Maps came out, and it was the worst release I can remember Apple ever doing. Android seemed to be pulling ahead in a lot of ways. A lot of people were saying that Tim Cook wasn't capable of running the company, and that the magic died with Steve Jobs. The stock price started to slide.
As we all know, Apple recovered from its bad release of Maps and revamped iOS, the stock price recovered, and there was much rejoicing. So, it's important to have a sense of perspective about these things.
Apple certainly seems like it has slowed down lately, but they have more resources available to improve the situation than any other company in the world. I suspect the current issues are caused by internal organizational problems rather than a lack of product vision.
