Uh, not big on verbosity, are you?
Seriously though, a bit more information on your shooting style/subject would be helpful if you want more useful comments. If you're already convinced that the D60 is the camera for you, then good for you. It's a great camera.
Image sharpness depends on a lot of things: lens, camera shake, subject motion, compression/sharpening algorithm, etc. The D100 has a somewhat soft JPEG engine. So JPEGs out-of-camera are not as sharp as they should be. This can be worked-around by shooting in RAW mode and/or doing sharpening in post-processing. Alternately, the Fuji S2's engine does not suffer from a soft JPEG compression algorithm, and produces very sharp JPEGs. Also, the S2 uses Fuji's rotated photosite grid, which squeezes a bit more horz and vert resolution out of the imager.
