Sure, camera sensors have gotten better and less noisy, but convergent technologies are primarily happening in the smart phone market, not the camera market. On top of that, statistics show that the most common cameras are now cell phone cameras, the iPhone in particular. Flickr reports that as of this posting, the Apple iPhone 4s is the most popular camera in the Flickr Community. If you add in the iPhone 4 and then the large upswing in the newly available iPhone 5 and the now waning iPhone 3GS, you have in the iPhone platform a huge lead in the number of cameras people are using to post to Flickr."
