Also I think Android spread like wildfire because it was owned by Google who allowed all manufacturers to use it for free, or may be at a lower price (I don't know). The key point is Android being available to various hardware makers contributed big to its success. If it had been owned by Samsung it would not have been different from Symbian or other manufacturer specific operating systems.
