Well actually Nokia could/can use "android" who says it has to be Google version of the OS. For example look at what Amazon did with the Kindle Fire they did a code rewrite made it look nothing like Google version, its more focused on consumers, they opened their own app store and built their own relationship with developers whereby devs get more per app on average even when compared to the Google Play store. Also amazon gets all the profits and nothing is paid to Google.

Nokia in the past with all of the brand value and services could have done exactly the same thing that Amazon and be even more successful, end of the day all that matters is Apps. Also WP7 market place may have currently have more apps but Amazon app store is showing exceptional growth.
