Don't forget about Firefox OS! Imagine what impact H.264 would do there. Firefox OS and Tizen are the BigBets now, because TelCo's manufacturers don't like to rely on Google for delayed OS updates anymore. That's why these OS have a good chance of becoming as popular as android in a few years. But that's only valid, when Firefox OS and Tizen get their shit together and finally create a robust, independent, secure and most importantly not only beautiful, but usable user interface.
(Firefox does silent upgrades, just so you know. Luckily on Windows only.)
