While Android and iPhone users have been enjoying Rovio’s hit Angry Birds game for ages, Windows Phone 7 users have had to wait through delays. Well, the original Angry Birds has finally arrived for Windows Phone. In this video, we demo the game to see if it performs as well as it does on other platforms, which it does. The free trial allows you to play through the first 21 stages and the full version offers all 165 finger-flicking levels of goodness. Check out the video below to see it in action, then hit up the WP7 Marketplace to grab the Xbox LIVE title for $2.99.
