I have never found a calculator for pocket pc to beat the Calc98 from calculator.org
I started using this calculator on my original Compaq 3600 (May it rest in peace). This calculator only has one memory location, but has full parentheses for complex equations, supports hex, octal, binary, even roman numerals. Converts anything under the sun, does matrices and statistical mumbo jumbo and even includes a periodic table of the elements under the cnst (constants section). Runs great on my apache running wm6.1. Not the most finger friendly application (small buttons), but I love it.
