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.
Good thing the 300 million minutes of Angry Birds daily..
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.
Are you implying that the Start Menu is for power users?
