The differentiation is that their whole widget is different to their competitors. It's an area they had to dominate and grow, just like Samsung did with Android. Obviously this hasn't worked quite as well for them.What nonsense, there is no differentiation with WP, all manufacturers have to use the same exact stock OS and skin. With android they could have made a phone that looks exactly like metro if they so wished or any other design they could possibly have come up with. If WP had swopped places with android then nokia would be just be another OEM, no software customisation, no unique skin or anything noteworthy. On WP you can only offer what MS allows and all the phones would look exactly the same.
