Maybe. Market / pricing power is not sinple to assess, and I'm not sure if device / OS side or the application distribution side is most relevant to the browser bundling decision. I'd say it' seems to me more likely that the Apple has pricing power in the App Store that in iOS devices (it doesn't sell iOS as such, so that's probably not the thing to look at), and either device or app store market power, if it exists, could be leveraged against competing browsers with the policies restricting them.)
