Don't underestimate the value of having a useful, programmable microcomputer as a ubiquitous element of education. These calculators are (were) a portal to computing, accessible in a way unmatched by any heavyweight system. What RaspberryPi, MicroBIT, PocketC.H.I.P etc were all trying to achieve, TI calculators (practically inadvertantly!) achieved to a level of success undreamt of by those systems. Every student in high school owned a BASIC terminal. That's huge.
