Back when mobile phones were becoming established as a ubiquitous, near essential part of modern life, camera phones were a big deal. At least, phone manufacturers seemed to think so as for a period it was the primary battleground for differentiating between models.
Of course, they were all abysmal.
One of the things I've enjoyed about owning a smartphone is actually having a moderate-to-great quality camera in my pocket at all times. While the original iPhone camera was definitely lacking, by the iPhone 3G S, photos in good conditions were pretty great. My iPhone 5S takes downright excellent shots in all but the worst light.
It's amazing to be able to capture some of the everyday spectacle of my walk to work, or a bright summer day in our woefully under-utilised garden.
