Again, this is really the reason for my careful response in the whole sensor size / camera discussion. When posting a downsampled image that has been converted to sRGB on the web, the advantages of a full-frame (or larger) camera are largely negated by the limitations of the smaller format. In fact, to oversimplify, the only advantage in the final result of a larger versus smaller sensor camera posted on the web is really the impact of background blurring due to the shallower DoF.
