500,000,000 downloads... 300,000,000 minutes... 0.6 minutes played per download? These numbers must include trials and people re-downloading on new phones. I'd be more interested in the number who have PURCHASED Angry Birds.

My guess is that people play the game on days other than that on which it was downloaded.
But maybe it's because I'm a Sys Admin.
