The image sensor in laptops and desktops are very similar in size...must be the quality of the sensor themselves and the processing that goes on that is responsible for the difference.

I wasn't aiming for accuracy. It's a simple and crude analogy, that even my mom would understand. Why one camera takes better quality pictures.
For what it's worth, your 35mm frame example would still hold true to the webcams. I have a few spare iSight sensors and the physical size of the component is larger than the one in my Mini 10v, which is also 1.3 megapixels.
