A little lesson on MP

Higher megapixel numbers are not always better. The sensor sizes do not change, do the pixels have to get smaller. That means they don't gather as much light. The D40 sensor will likely give you better low-light performance than the sony. But compare them in the store. Set the ISO, f/stop and shutter to the same setting, and take a picture of the same subject, without the flash. See which one is more sensitive.

Besides that, if you don't print, or print 8x12 or smaller, then anything over 5-6 Megapixel is a waste.
