Re ignoring feature phones: Good point. Making a distinction between feature phones and smartphones gives us the choice to not support the former. At least in the USA, it's probably rarely worth the effort. (Don't know about other markets.) Native is sometimes the way to go, for the reasons you mention. It's also AT LEAST an order of magnitude more expensive - especially for several platforms...
