Five dominant threads inthe discussion
| Theme | Core observation | Supporting quotation |
|---|---|---|
| 1. Premium price for a “captive” market | The $160 price tag is repeatedly called a gouge on students forced to buy the only exam‑approved device. | retired: "For a $10 BoM and maybe a year of R&D I would say that $160 is bad." |
| 2. TI calculators as a launchpad for programmers | Many HN users trace their first coding experience to a TI‑83/84, crediting the device (and its BASIC/Python support) with sparking a career. | joebates: "Same. I learned programming on that calculator." |
| 3. Exam constraints lock students into approved hardware | Tests still require a specific calculator model; alternatives like Desmos or phone apps are often barred despite being technically viable. | sosborn: "You can use any calculator that meets the restrictions for things like the SAT." |
| 4. Cheaper or open alternatives exist | Casio scientific models, NumWorks, and open‑source emulators can meet the same functional needs for a fraction of the cost. | xbar: "Your corner drugstore sells an AP/SAT approved calculator for $9 to $29." |
| 5. Stagnant hardware & calls for openness | The Evo’s 156 MHz ARM processor and 3.5 MiB of RAM are viewed as laughably low compared to modern phone hardware, and users urge TI to innovate or open the platform. | retired: "This has a 156Mhz processor. My lightbulb has more calculating power than that." |
These five points capture the most‑repeated concerns: price gouging, the calculators’ role in early programming education, exam‑driven buying restrictions, the availability of cheaper competition, and the need for genuine hardware/feature upgrades.
