I'll downvote you because I think you're missing the point.
Android makes Google $2.5B/yr (that's a run rate, up from $1B this time last year). Google's total run-rate is about $35B by comparison.
Given that it's in land-grab mode, I imagine they are re-investing like crazy in Android-- they realize that the dominant smartphone operating system has a lot of market power. As an example, Microsoft makes more on Office/Server stuff than they do on Windows.
tl;dr Comparing a dominant operating system (Android to a hardware company that grudgingly made software (Nokia) isn't really valid.
