One of my calculator-collecting interests/obsessions is special-purpose calculators. While calculators designed for specialized applications have been made by several manufacturers, Calculated Industries is the current reigning expert (since 01978) in offering calculators preprogrammed for different specific uses.
A lot of the things being done by CI can be accomplished on a standard programmable calculator or on a PC--indeed, the I'net is teeming with downloadable software for many of the applications covered here--but there's something undeniably cool about having a highly specialized machine available for your particular calculating needs.
