Here's a similar article without the paywall I ran into at WSJ: http://www.businessinsider.com/apple-92-percent-profits-enti...

I noted that Apple is responsible for less than 20% of the industry in terms of units sold last quarter, but makes over 90% of the profit. Considering the prices of a Galaxy S6 and iPhone 6 aren't that different, there is something way different between the operations at Apple and the competition (read: Samsung). The difference is in profit margin, but it's not obvious where (at least to me). Samsung should have great deals with it's affiliates of the same name on chip and screen prices, and it can't be that it's factory conditions are much better than Apple's.
