"Huh, Angry Birds Space is out," I thought last week, and then I bought it without really thinking. It's that kind of casual, absentminded purchase that has propelled the game to an astounding ten million downloads.

Rovio announced through the Angry Birds Twitter account that its new game hit that milestone "in less than three days." As of last year, the other three Angry Birds games had been downloaded half a million times.

We're sure the takeaway from all this for some of you will be "Huh, Angry Birds Space is out." And thus the cycle continues.
