If you want to believe there is nothing that can truly compete with the iPhone because of its magical UI or lack of features or whatever I can't prevent that. Yes, it's true, the iPhone is the only iPhone in existence. But in that sense nothing can compete with Android either. Nobody else is producing an open-source smartphone os even close to its quality. If you get specific enough, everything is in a category of its own without any competition.
My original comment has nothing to do with whether Apple has produced the perfect mobile os by reducing and removing features. It has to do with the statement that Apple has no real competition.
