Too much of a generalization.  You can get exceptional B&W from a scanner,
which most all use RGB sensors.  Also, scanning backs use RGB and give full
color data, and they convert very very well to grayscale.

Well, if you're talking cameras, Kodak has, and if you're talking scanners,
the Leaf was.

To a degree, I agree...but it isn't as bad as you make it out to be.  Have
you actually done any experiments, or do you know of any on the web?
