The Overpriced Calculator
In a world where Apple and Samsung are expected to innovate and manufacture amazing new products every 12 months, the graphing calculator remains an anomaly.
For decades Texas Instruments has controlled the market with their line of “TI” graphing calculators. Since the 1990s the technological advancements of the TI calculators have been limited; with little advancement in the low resolution screens and minimal onboard memory.
Meanwhile, the cost of the calculators remains inflated. As of this writing, the price of a new TI-84 calculator hovers just over $100 on Amazon.
A software company named Desmos is trying to disrupt the Texas Instruments monopoly. The San Francisco based start-up has created a web-based calculator that is free for teachers and students.
