Apple started running a new iPhone ad this evening called "Photos Every Day". The ad is a departure from recent iPhone advertising, focusing on people actually using the phone, rather than just the phone itself.
The ad finishes with the above quote, likely referring to statistics from Flickr that show the iPhone as the most popular camera on the service. Three of the top four most popular cameras on Flickr are iPhones and Apple has put a lot of effort into improving the camera in the iPhone over its past few iterations.Every day, more photos are taken with the iPhone than any other camera.
Apple's most recent iPhone ad campaign used a series of words flashing across the screen to showcase a number of different iOS apps.
