It seems right now like Google’s Android operating system and Apple’s iOS platform will be the world’s most popular mobile operating systems forever. After all, every mobile OS that came before them, and everything else that has come along since these two platforms took off, has been crushed. Of course, those of us who have been around long enough remember that at one point in time, Nokia’s Symbian platform seemed like it would reign supreme forever. Platforms like Symbian, Windows Mobile, and BlackBerry OS used to dominate the global market, and now they don’t even exist anymore.
