Update: Microsoft has quickly pulled the questionable material from its YouTube channel.
The videos poke fun at Apple's design process for the iPhone 5s and 5c, showing satirical Apple product review meetings where two "employees" attempt to pitch various features of the new phones to actors intended to resemble Apple CEO Tim Cook and Senior Vice President of Design Jony Ive. The iPhone 5c's case colors and the iPhone 5s's 8-megapixel camera are among the items featured.
One of the videos, entitled "A fly on the wall in Cupertino - Polycarbonate," takes Apple to task for choosing a polycarbonate backing for the new iPhone 5c. This appears to be a bout of cognitive dissonance on Microsoft's part, as the flagship Windows Phone devices - Nokia's Lumia series - are similarly offered with colored polycarbonate shells.
There are seven videos in all, running from twenty-eight seconds in length to two minutes and twenty-eight seconds. Each video ends with a stark black screen and the hashtag "#timetoswitch."
