I'm not worried, Apple can't and is not going to compete in the cheap android phone market. Profits are important but as has been suggested by BH buying Apple, the company has changed and will continue to thrive.(and no it's not going blackberry)As an investor, I am happy to see Apple continue to make profits, but the lower quarterly results and reports like this are a concern.
As a purchaser, I am interested in buying a quality product and the ranking on the world stage should be only a minor input into my decision. It is nonetheless an indicator to consider, given some recent quality issues. On the whole I am still attracted to the whole Apple ecosystem and cross platform integration.
Rankings like this, however, suggest that the differentiator is becoming less so, as others are building out their own ecosystem and improving quality. Apple next steps will be very telling.
As long as Apple makes products I like to use, I will buy their products no matter what the market share.
