Angry BirdsThe incredibly popular Angry Birds mobile game has finally landed on the Windows Phone 7 platform. Versions of the game already run on the iPhone, Android, webOS, B&N Nook, Intel AppUp for netbooks, and the Chrome web browser.

Angry Birds is one of the most popular games in the world and has had more than 200 million downloads. The game’s developer, Rovio, has released other versions of the game like Angry Birds Rio and Angry Birds Seasons, and it even plans to expand the brand with all sorts of merchandise and a TV show.

The Windows Phone 7 version is priced at $2.99 in the U.S., which is more expensive than its iPhone and Android counterparts. The iPhone app runs for 99 cents, while the Android version is free but has advertising.

Windows Phone 7 launched back in November, and it’s taken quite some time for Angry Birds to appear on the platform. After including an unapproved Angry Birds icon on WP7 launch materials, Microsoft said the game would arrive on the OS in the spring. Apparently it’s a little late, but late is better than never when a game has lots of hungry fans.
