Bottom line: This phone will sell just like any other iPhone will. Why? Because Apple has made the iPhone synonymous with smartphones and it's not because of people being sheep it's because of marketing. It's the same reason Apple dominated the mp3 market and made everything else an afterthought. Most importantly people find comfort in picking up the iPhone and being able to just use it without much thought. I know for some of you that, in your mind, makes the phone inferior but it's true.
In the past this was the case... to a lot of people iPhone is smarthphone and anything else was just a cheap knockoff. But that's not the case anymore Samsung is getting a lot of mainstream recognition now. And just like how before it was "cool" to own an iPhone... now it's "cool" to own a Samsung Galaxy S3. So not as many people will blindly buy iPhones as they get a chance to see friends with Android phones in action and realize it's not what the detractors claimed to be... meaning Android is a complicated software for tech geeks.
And you say they are not sheep... it's just marketing. That's exactly the definition of a sheep... they don't think for themselves... they just do what Apple marketing tells them to do!
