Aside from the stupid hyperbole that Apple’s profit is “95%” (yeah, let’s see someone else build with the same cost base and make an Apple-slaying killing on a mere 5% profit)...
Apple HAS made enough profit that when comes time to significantly improve the technology, they can write a big check and build a factory capable of producing next-generation technology at near-commodity post-depreciation prices. Everybody was ready for “retina” displays, but nobody could afford the cost/risk of building the factory ... until Apple wrote a $1B check for a display maker to build a new flat-panel display factory capable of such resolutions, thereby instantly depreciating the cost so panels could be sold at commodity prices and Apple could reap roughly 50% profits on what competitors would spend twice as much to build.
Apple’s overall margin, across the enterprise was about 40% last quarter.
