The thing is, if we buy a large-resolution camera, that indicates we plan to crop into the pictures or some way use the pictures larger than we would the lower resolution image. If not, why bother? And that is the point where I think the article comes up a little short.

OK. You want to crop hard on the photo from a high MP camera. And the result has a lot of noise.

Now ask yourself one simple question:

If you had taken the same photo with a low MP camera and cropped it to the same ratio of the full image and enlarged it to the same final size, would it have had less noise?

If your reply is: "I would not do the same cropping to the low MP photo", then you are not comparing the cameras on equal terms.
