"I’ll admit flexibility is a strength of Android. Conceptually, I like that I can change almost anything about the OS. I can download an app to fix something I don’t like about the OS, and the OS doesn’t mind. And if I really hate something about the OS, there’s always the option to root and go completely nuts. But a few weeks into owning my Nexus 5, do you want to know the truth? I easily get frustrated in customizing - it is a never ending task."
