Replaces my physical hp calculators for most tasks

Although not programmable and lacks graphing capabilities, PCalc 4 for Mac in RPN mode replaces my hp calculators for many Engineering tasks. With a few adjustments, I made the Mac version look identical to my iPhone’s copy in landscape mode and this is great for having a consistent layout of buttons. I like their choice of “42” for universal constants and A>B for many conversion factors. You would be hard pressed to find an equivalent physical calculator, or a competitor’s virtual one, for the price of PCalc.
