Graphing calculators are pricey because they are pocket-sized computers with downloadable software and relatively big screens.
Four-bangers are single-chip devices that are hard-wired for what they do and using smaller, way cheaper displays. They *really* are different types of devices. It's not a profit margin thing, like with the high-end tablets which all use comparable components.
Anyway, math teachers use the TI calculators for the same reason businesses use Windows: the price is acceptable *and* the apps are there. Software drives use.
