I think you overestimate how much consumers care. Look at RROD, YLOD, antenna gate, consumers don't seem to care...most people have decent internet access. If they didn't things like iPads wouldn't be flying off the shelf. Yes there are pockets of the country with horrible online that would make it impossible for them to use online devices like tablets and always-online game consoles, but I just don't think MS cares to lose that segment, as they probably figure they are small enough minority and will only shrink over the next 5 years.
I think this is really revisionist, don't you? RROD cost Microsoft a billion dollars as they attempted to head off a class action lawsuit. Antenna-gate generated enormous negative press and required Apple to hold a public press conference addressing the situation and give away $20 add ons for free. Then they changed the design in their next iteration. PS3's failure rate is not too dissimilar from historical norms, so I can't really comment.
Consumers can get loud on these things. That they keep buying them suggests satisfaction with their resolutions, I think.
