Despite all of them being counted as a single model, this fact is still impressive: The iPhone is now the number one camera in Flickr, the most popular image network. It's also the only cellphone in the top 5.
I've to admit that I used to tote my DSLR or a point-n-shoot everywhere, and now I don't thanks to the iPhone. Whenever I need a snap, I just take out the iPhone and fire away. I miss the quality and flexibility of my real cameras. And I really wish the iPhone had a camera as fast and good as a nice point-n-shot. And I really really REALLY wish for instant camera access and a physical shutter button. But even with all those missing features, it's oh-so-much more convenient. And most of the time—I hate it sometimes—I just care about the moment.
