If your idea is indeed "N9 with Android" just get an Android device. You wont ever see Android apps to N9.

All of the Android, iOS and WP give a better everyday phone with 100% support and hundreds of new apps appearing everyday.

N9 has it charm and i use it every other day over my iPhone 4 and Lumia 800. Though you really need to be in love with the multitasking idea and swipe UI, that i'am. Because that's really what makes N9, N9 imo.
