One step forward, two steps back. On the same day when they actually do something relatively cool (adding Twitter search to Bing), Microsoft had to go and ruin all that goodwill by producing another unfunny video. To boot, this one, set in an app-creating lab, spoofs the large number of gag apps available for the iPhone.
Takeaway: Apple is fun and user-friendly; Microsoft is bitter. Not sure that's what they had in mind.
