Clearly, you have not been paying attention. It is obvious that Wintel OEMs do not think like Apple, but thinking differently is just the start of Apple's advantage. An essential element of Apple's advantage is its massive cash horde. It uses the money to build factories for its contractors that no combination of competitors can emulate. Apple cornered the market on the machine tools used to fabricate the aluminum bodies of its laptops. Everything goes under the microscope--from the raw aluminum for its laptop bodies to the last mile delivery to the customer. Part of this process is a complete study of every cost to produce everything. In that, Apple squeezes all identifiable costs to the bone.
You may fantasize about the ability of the Dells, the HPs, and the Lenovos to compete on production costs with Apple. In a drug-induced state, you may even fantasize about the white box OEMs competing with Apple. But in the real world, Apple has production advantages that are secure for the foreseeable future.
