Even when you begin to deconstruct the values in switching to a different OS the conversation becomes stereotypical. iOS vs Android; evil vs good. The most widely used mobile operating systems define the polarisation of software technology. Each representing the values of closed systems and open systems. But I’ve been recently looking for an alternative. CyanogenMod is an open-source operating system for smartphones and tablets, based on Android. It is developed as free and open source software based on the official releases of Android by Google.
