Yes ! But profit margins for PC sales are razor thin since it is a commoditized hardware nearly. But profit margins from Smartphone sales are much higher - and I am sure each manufactirer (HTC, Moto Nokia) will try to protect the margins - and thats where the differentiation comes in. None of these players want the smartphone to become a commodity hardware running the same OS underneath, if they want to enjoy the profits - and its in Smartphones segment that the greatest profit margins are.
