Finland seems like a pretty cool place. They've given the world saunas, the Linux Operating Systems, and Angry Birds. Not a bad list of accomplishments, no wonder they have one of the highest qualities of life on the planet.
According to Rovio, over 30 million people downloaded a version of Angry Birds from December 22 through 29. Rovio also mentions the eight million Angry Birds downloads that occurred entirely on Christmas day.
Angry Birds Star Wars has been in the top spot in the App store since its launch back in November. We don't know what $4.99 multiplied by 30 million is, because we're bad at math, but it's more than enough to keep Rovio warm through those Finnish winters.
