K-maps are useful when dealing with programmable logic devices at the
hardware level. I have not used them when doing actual logic design,
but that is more because I am primarily software, and have only
designed a few simple peripherals mostly built around off-the-shelf
VLSI ICs and some glue.

I do tend to agree that with today's modern design tools, K-maps are
an anachronism for large-scale design. But large-scale design is not
the only thing out there... for certain small-to-medium sized tasks,
such manual mimimization techniques can be quite helpful.
