Winning like the 90s is nonsensical
Maybe I'm mistaken, but I think this whole discussion is off base. Eric Schmidt brings up Microsoft-Apple, but that was the 90s. The OS wars don't make any sense anymore - especially not for mobile. The ease of mobile development, the basic functionality of the phone, and thus the interconnectivity of the devices means that a developer can reach every device of a particular operating systems. A developer can cater to a niche market, where as long as they will buy or otherwise spend money on the app, they will have success. iOS has a healthy app ecosystem - tested and proven for app-makers. The difference between now and the 90s is that doesn't change as much with a smaller market share. Microsoft trounced Apple because it gained such a wide-margin over market share that developers found it too cost ineffective to develop for it and retailers wouldn't stock Apple software. Thus people wouldn't buy Apple products because they couldn't use their favorite applications and people didn't develop for Apple because it was too hard to reach the few people who owned a Mac. However, those issues are ameliorated significantly when you have digital retail and app development has come a long way since then on all platforms. True Microsoft and BlackBerry have more limited ecosystems, but unlike the 90s, because they are down, doesn't mean they are (necessarily) out. I see a lot more fluidity in the mobile OS space than the computer OS space and the computer OS space is healthier than it's ever been. OS X still has a much smaller OS-share than Windows, especially around the world. However, the app ecosystem for OS X is better than it has ever been. Part of that is because of increased market share in the US, but part of that is digital retail and better development tools make it easier to develop for and sell to customers regardless of how small your market share is. There may be a limit to how many OSes the mobile market can support, but I bet it's more than two and won't end up with one completely dominant as the 90s OS wars did.
In short, iOS has a healthy ecosystem. Android has a healthy ecosystem. WinPH8 and BB aren't quite as healthy, but again things are more fluid. "Winning" doesn't mean what it used to mean. If someone likes Android, great! If someone prefers iOS, good for them! It doesn't matter. Their consumer choice is unlikely to affect your ability to get the next device of your preference or have a healthy ecosystem for your device. No one has market share dominance like the 90s, it is not clear anyone will be able to achieve that kind of dominance, and it won't matter quite as much even if they do.
