Calculator features multiply

The applet with the most visible changes in Windows 7 is the lowly Calculator. It now offers four modes (standard, programmer, scientific, and statistics) and a calculation history window (much like the paper printouts from adding machines of yore). Perhaps most interesting is the new pane on the right side, which can perform date calculations, unit conversions, and various financial calculations.
