That's the thing main users already have Samsung galaxy 3 and IPhone5 that's over 40+ million customers. So Lumia range will be for those who already haven't bought SG3 or I5. But on the other hand everyone I spoke to absolutely hates windows phone and it's interface and would rather wait for next big android.

I am not market analyst but it's obviously Lumia sales are quite ****, I hope it does good though, I don't want to see market dominated by Android and iOS
