The problem is Apple only sell one (well 2 designs in reality) phone. Android (your example) runs on many. Far more options on design, colour, size and specification. Same with Windows Phone.
I know this forum is obsessed with specifications but in the real world it's not that clear cut.
I suppose that's true, but in the real world the iPhone rules its price bracket due to the fact it's made by Apple and the design/quality is arguably the best.
