Computerworld reports that several of the "I'm a PC" ad images that were posted to Microsoft's website were created on a Mac.
Four of the images that Microsoft made available on its PressPass site today display the designation "Adobe Photoshop C3 Macintosh" when their file properties are examined. The images appear to be frames from the television ads that Microsoft will launch later today.
The images likely originated from the Crispin Porter + Bogusky ad agency that is responsible for the ad campaign.
