Dear all,

I generally agree with Mike's argument that pixel count isn't everything. But he did miss the following points:

1. Higher pixel count will likely to enhance the colour accuracy of the current RGB mosaic type CCD sensors. More pixel will increase the information available for interpolation calculations.
2. Higher pixel count will enable greater flexibility for cropping.

I believe that there is an optimal size of an image sensor which a balance must be strike between the resolution, greater choice of DOF, optimal design for both wide-angle and telephoto lenses, and the compactness of camera body. Eventually, digital camera will evolve into an optimal design, like film sizes in traditional film camera. In the traditional film, 35mm format is the most balanced design. If one want to go for better quality, you can have 645 or 67, while for more compactness we have the APS format. But 35mm format is still the most popular. Digital evolution will be the same. There is nothing to do with the pixel count.
