So as we all know now, Google and Apple are engaged in smartphone WAAAARRRR 
It soon becomes clear that the Google-owned properties (Youtube, maps) aren't best served by the native iPhone apps for them, e.g. Youtube is MUCH more functional through Safari and Google Maps on an Android is supposed to blow away the iPhone version (turn-by-turn directions anyone?). This isn't to mention other Google products such as Gmail, Docs, Latitude etc that don't even have native Google-produced apps.
So my question is; who's at fault for holding back these app developments and why are the best features only accessible through Safari web apps instead of being native?
