This would apply only to JPGs, right? If not, did the review give directions to change the settings, or are you meant to figure it out on your own?
I wouldn't fault them for that - most people won't know how to do post-processing stuff to get the most out of their images, nor will they tweak the camera's processing settings either. Yet, they're likely to bitch when they don't get the results they're looking for (those "pro" results.. since they just shelled out all that $$ for an slr, right?) So yeah, they took it into their own hands.
Having said that, lately I've really started nailing down the perfect image optimization settings for my D200 (hue, saturation, contrast, sharpness, color mode, etc.. ) I've also been using the tweaked custom WB settings (most people don't know that there's a +/- 3 setting for EACH white balance mode. So for sunlight, cloudy, incandescent, etc.. you can have 6 specific modes to tweak the color for each. (hold down WB buttom, command dial (rear) toggles overall WB mode, sub command dial (front) controls the "tweak" for each mode.) I've had particularly good results with -1 and -2 direct sunlight WB, casts a really nice warm tone to pictures.. bump it up to -3 for sunset/sunrise stuff. Most of what I do is sports stuff in fields anyways, so it's nice to have a tone like that to your images.
Anyways, back on topic. The only thing I'll take on the D70 is the CF slot. The D80 is (these are facts, not opinions..) faster (shutter lag, viewfinder blackout, and the fact that it's processing 10mp instead of 6) more accurate (CAM1100 AF, 3D Matrix II metering, more i-TTL control) more durable (beautifully constructed chassis/control layout) and has a big, bright, accurate viewfinder. It's also a LOT more customizable (custom / shooting A/B/C modes, custom menus, and custom function buttons.)
It's just a better machine guys, no way around it.. kinda an evolutionary thing. But considering how old the D70 / s are, it's still holding up very well.
