Perhaps
One could imagine a world where different people had different beliefs about which OS was best, yet still held respect for others who believed in another OS, be the platform a mobile phone, a desktop or even a server.
Once people came to respect others preferences it might come to pass that there was peace across the universe, extending even as far as the darkest corners of planet Earth where it had been foretold that man shall usurp his foes at any cost.
In the meantime (I can't wait for hell to freeze over), wouldn't it be nice (?) if in the mobile world one could buy a device that came with a preinstalled OS (optionally) but one could choose another OS (iOS, android, windows, ...) without voiding the warranty.
