Maybe the engineers thought a business calculator was just too boring for their hardware?
The calculator is based on an Atmel ARM chip, and has a bootloader and JTAG interface to allow user applications to be written and downloaded, turning a boring calculator into anything you can do within the constraints of the hardware.
