Why Are Students Still Required to Buy Graphing Calculators?

In observing April Fool’s Day, AOL’s gadget blog “Engadget” has posted a raft of reviews for technology from yesteryear.  One such review is of the venerable graphing calculator TI-83 Plus.  The reviewer writes that even ten years after its introduction in 2002, the calculator still functions great but still costs a whopping $85 for what he claims is only “about forty cents worth of technology,” which begs the question — Why are students still required to buy these things when their iPhones and iPads can run circles around antiquated graphing calculators?  You might not like the reason the author postulates.
