I've heard it said the best camera in the world is the one you have with you. I'm finding this to be more and more of an accurate statement since I've been a dad. I don't always feel like lugging around my DSLR, but I always have my iPhone. While lacking in overall quality, most photos taken with the little 2 mega-pixel built-in camera can be sufficiently "fixed up" with photo editing apps available for the iPhone.
For the photo shown, I snapped the pic in the shade and used an application called "Photogene" to convert to black and white, crop, and adjust contrast--all before the photo ever left my phone.
The real value of a shot like this is that I captured a moment I would not otherwise have captured. I didn't have my Nikon, or even my wife's Coolpix with us, but I did have my phone.
