Apple may be a one-eyed man in the realm of the blind, but even so that does sometimes make them king. Apple doesn't do anything that the rest of the industry can't: they coordinate good usability and aesthetic design with strong execution and solid brand management, but the rest of the industry doesn't. And that will continue to give Apple a huge competitive advantage until the rest of the industry wakes up and "gets it".
