I think they've already tried, their attempt was called "Firefox OS" which ran web apps exclusively. I don't think they have the skill or clout to pull it off.

I think they've already tried, their attempt was called "Firefox OS" which ran web apps exclusively. I don't think they have the skill or clout to pull it off. And I don't say that as an insult, not even Google could really pull it off, although they're still trying. Native app performance is too far superior, even now.
