Myself, to be frank, I've always looked at B&W pigments as a pain. One completely has to change the way one uses an inkjet printer, alter it in a fundamental manner, and make it useless for normal functioning.
I've seen the results of more accessible technologies like ImagePrint and Epson's Advanced B&W, both of which use a printer's standard ink set, and the color constancy of the results among light sources is remarkable. (Yes, color constancy, not "metamerism", in case someone feels compelled to "correct" me...)
Not to mention that both these latter technologies allow for a range of toning options as well, which B&W pigments don't, at least not nearly as flexibly, or with as wide a range of possible hues.
Occam's Razor suggests that one ought not look for a complex solution where a simpler, more parsimonious one is proven to work. (Well, Occam's Razor actually concerns simple and complex THEORIES, rather than TECHNIQUES, but I think that the analogy holds, or at least offers room for thought.)
