John Watkinson of Larva Labs on how much money iPhone developers make vs. Android developers:
Overall we estimate that $6,000,000 has been paid out to developers for games, and $15,000,000 has been paid out on apps. That is a total of $21,000,000, almost 50x lower than the amount paid out to devs on iPhone.
Apple announced that iPhone app developers have been paid $1-billion already.
