John,
The Monochrom offers a lot more than a little more resolution and detail, how about 30% more resolution because it has no Bayer Filter Array. To one poster 30% is just a little which I find amusing.
While my Monochrom the "Clunker" can't do color the fact is that it does B&W exceptionally well. Big prints don't lie, and you can't print whats not there.
Not for everyone, will not do color, but for B&W only it is the way to go.
