Apple's Market Cap Declines By $50 Billion

Apple had a reasonably good quarter.  It sold 48 million iPhone's and 23 million iPad's, and revenues grew by 18%.  However, investors demand more from Apple.  It's shares fell by 10% after its announcement.  Samsung has proven to be tough competitor for the iPhone, and the margins on the mini iPad are 6% less than the original iPad.  Apple operates in a world of high expectations.  Investors have come to expect miracles from Apple, and they are disappointed when Apple only grows by 18%.
