Apple cannot expect that it would hold a monopoly on an idea that just needed massive market uptake. Besides, Apple has no interest in making iPads affordable to ALL people, and, by trying to cock-block the market of derivatives or alternative but very alike-looking tablets, Apple would deny others similar functionality. It wouldn't like that if it were barred from making laptops...
Apple knows how blend tech and sexy appeal. That's their biggest strength. But, it is not the only way to live.
