Looking for something to take camping and bicycling with my wife, I have held the G12 in a camera store in nearby Tempe, and like the flexibility of the viewing screen among other features. It is that feature that is keeping me from buying either the G12 or the Nikon P7000, while carefully considering what both offer. While the Nikon's viewing screen is fixed / stationary, the Nikon offers a little more telephoto with its zoom. I have a Nikon speedlight that is compatible with the P7000. However, the Canon keeps "talking" to me as the one to purchase.
Anything that you could add - suggest would be appreciated.
