Classic example of "I can't think of a use, so it must be useless". bc is very useful, and I can think of several times one might need a command line calculator.

Commands like 'arch' might provide a limited amount of data from a different command. However, to extract just the data from the larger response would then require a string of grep/sed/awk. or call the one command to give you the output you specifically need. This also holds true for the 'uname' section.
