The death of calculator market?

[carey]

An example of the power and convenience of CAS calculators over desktop and mobile alternatives is that they easily handle symbolic matrices (e.g., matrices filled with polynomial elements) which popular open-source numerical software (e.g., NumPy) cannot. While symbolic matrix operations are available in desktop and mobile CAS systems they are seldom as convenient to use as in a CAS calculator.

Admittedly, symbolic matrices (useful in control systems) are not a common use for calculators, but they represent one among many long-standing strengths of CAS calculators over non-calculator alternatives. So paraphrasing Mark Twain, "reports of the death of the CAS calculator market may be greatly exaggerated."
