I just went through my X100 gallery, and deleted a few shots to keep it slim and trim. The effort left me with 61 photos. Out of those 61, only eight benefited from color, and two of the eight are of the Sunkist orange bottle. The other shots I kept were either shot in color and then converted to black and white before posting, or were originally shot in black and white. In my film gallery, of course, there are even fewer color shots, proportionately.
This tells me something: I am not a color guy; color - with very rare exceptions - just does not fit the way I see. This removes - for me - one of the four basic reasons for a digital camera. I just plain like film black and white film better because it fits the way I see.
Now, the other basic/key reasons for a digital, in my experience of eight months with the X100, are convenience of oh-so-quick processing, zero film expense, and extreme flexibility of ISO. With one of the four basic reasons for me to own a digital - the only aesthetic reason at that - knocked out, will I ever be a digital guy?
