iPhone 4S Becomes Second Most Popular Cameraphone on Flickr
Apple's newly launched iPhone 4S has quickly shot up to become the second most popular Cameraphone on Flickr.com. Flickr's Camera Finder page shows graphs of the popularity of both smartphones and Point and Shoot cameras.
The iPhone 4S has beaten out the iPhone 3G, iPhone 3GS, and HTC EVO 4G, but still lags behind the original iPhone 4. The iPhone made headlines in 2009 when it became the most popular camera on Flickr, even beating out all dedicated non-smartphone cameras. The iPhone 4S still has a ways to go before dethroning the iPhone 4, which remains the most popular overall camera on Flickr.
The iPhone 4S introduced a number of significant improvements to its camera, drawing praise from many. Arstechnica recently posted a comparison pitting the iPhone 4S camera against several others, and found the 4S with competitive image quality and the advantage of convenience.
