And a person would have to be completely out of touch with reality to believe that Apple doesn't pull ideas and inspiration from the competitors.
If Apple releases a 4 inch screen iPhone, is it "copying" Samsung and their Galaxy S line? If Apple releases a dual core iPhone is it "copying" HTC, Samsung, LG, Motorola, etc?
The real truth is that it's a two-way street. No single company holds all the cards in their hands.
