It was always about Screen Size and Price vs iOS. It was never about Android vs iOS.
People left the iOS environment because they preferred the larger screen. Androids are mostly for the pragmatic and the tech-savvy. Some were unwilling to pay premium to use iOS when Android performed the same basic functions in a "fundamental" way. Tech-savvy people who were so entranced by specs would have also chosen Android devices.
Now though, with the iPhone 6 and Plus, people are flocking to the user experience of iOS. They even swallow the premium price.
Most tech-savvy people I know aren't easily enchanted by specs. It's the ones with just enough knowledge to think they know it all who sink into the specs glory hole.
Tim Cook on Apple's competitors:
Google is the top [competitor]. And then they enable many people in the hardware business -- like Samsung. And Samsung is the best of the hardware companies in the Android sphere.
He gets it.
