"The most popular mobile game in history now has been downloaded more than 500,000,000 times, according to maker Rovio Mobile. Good thing the 300 million minutes of Angry Birds daily playing time around the world aren't being wasted or anything. Rovio chief executive Mikael Hed says: 'This is a fantastic landmark achievement for us, and we’re extremely delighted to see such an incredible amount of people enjoying our games. We remain committed to creating more fun experiences and bringing exceptional quality to Angry Birds Fans everywhere.'"
Personally I dislike portable gaming, but it might be because I own a blackberry and I honestly don't mind waiting in lines or just staring at people and the world for short periods. I also just pack a book for those occasions (airports etc) where I'll know I'll need something to do. But 500 mil is still impressive.
