Re: higher sensor resolution (pixel density) gives focal length advantage

In most cases I'd rather have a 10Mpix picture made with Oly E510
sized-pixels than a 3Mpix picture (after cropping) taken with D700
sized-pixels

Fair enough, but that's not your only option: you can take the same picture with the D700 and increase the focal length, eliminating the need to crop out pixels on the D700 sensor. Extra weight and expense? Sure. But the image quality will be better.
