How long will it take for google to realize what they have in the nexus brand?

the nexus is a great phone. i love it. but i have to say that i am extremely disappointed in the lack of refinement. i am talking about the corners they cut because this is a dev phone.

crappy camera software. crappy display software. etc etc.

what are the odds of google pumping a bit more money into the software side to further refine their os into something spectacular? they have the sales now. you would think this would be a wake up call. in googe terms... software refinement doesnt equal higher pricing. it equates to more people clicking ads on a device they control.
