High P&S ISOs: B&W vs. Color
Ted Matsumura, Fuji F30 shot at ISO 3200 (click on image for larger version)
Ted Matsumura posted an interesting thought in the comments, which is that he uses his Fuji F30 up to ISO 800 in color but finds that 1600 and 3200 are practical in B&W mode. His blog is here. I think Mitch Alland actually prefers higher ISOs with B&W P&S shooting because it gives a rougher, grainy aesthetic similar to that of 35mm high-speed films.
