This situation today is a de facto duopoly. Those who benefit are most fundamentally Apple and Google. This is born out by the stock market and the Interbrand 100, where Apple and Google are respectively the #1 and #2 most valuable brands in the world today. The fact that both systems work by forcing everyone to purchase software through either the Apple Store or the Play Store and to use the same antiquated interface and decades old data storage system is further evidence of the duopoly.
