It's not so much a failure by the competition. My point is that Apple raises the bar so much by building a custom chip. A custom chip raises the bar on user experience: faster bluetooth connection times, longer battery life. What does the R&D cost for that chip? $100 million? Thats a complete guess - but totally within the realm of possibility given how much cash Apple sits on... Do you think the next viable competitor can spend that kind of money?
