Mac OS X: Calculator replacement

One of the most useful tools in OS X is the Calculator. To be honest though it is a bit limited. For instance, it doesn’t have a percentage function.

Enter R.L.M. Software, which has created several emulations of HP’s well-loved financial and scientific calculators for the Mac. I downloaded the simulator of my own HP calculator, the 10BII. This has all the functions of the real thing, plus a lot of other useful features like voice feedback, register and paper tape views. Not bad for $11.
