Nikon’s smallest digital SLR combines a 10.2-megapixel CCD with a simple, intuitive operation designed to take great, high-resolution pictures. Thom Hogan has a review of the Nikon D40x and writes-

"…the D40x does a bit better than the D80 in the noise department, apparently due to slightly more aggressive noise reduction, as the level of detail is slightly lower at ISO 1600 on the D40x than it is on the D80. But again, ISO 100 to 1600 produced very usable images.
…
The D40x retains all the things that are likeable about the D40 and gives you a 10mp sensor that produces images that are arguably slightly better than the D80 can produce (at least for JPEG files). You pay for that extra resolution two ways: extra dollars up front and reduced flash flexibility due to the all-mechanical shutter. I don’t expect to use my D80 much any more with the D40x being smaller and lighter. But someone with older AF lenses or who needs one of the D80’s additional features might choose differently."
