Apple is at the top of the food-chain in any of its five major products: iPhone, iPad, iMac, MacBook and iTune. While it cannot maintain the high profit margin, it can drop the price to cannibalize the products on the lower part of the food chain. The result is revenue grows faster than profit. The challenge is to meet the demand, not that there is not enough demand. The market is over-reacting. There are plenty of guys who has made a lot of money on this stock. It is time to switch hands.
