This article suggests the basis for the price is a result of lobbying to make calculators manadatory for certain tests. This rings true to me - even TI's comparison page (https://education.ti.com/en/product-resources/graphing-course-comparison https://education.ti.com/en/product-resources/graphing-cours...) has a section on test requirements but not on actual product features! However the argument for why this might collapse seems to be that technological change - touchscreens, phones, tablets, apps etc - means that institutions will be more willing to break from TI's grip. I don't believe this is likely. From the point of view of those institutions, saving student's money isn't a high priority. They are more likely to care about how a single use-device makes cheating hard. Not to mention the fact that despite the article's love of convergence, physical calculators are genuinely much easier to use for calculating than a touch screen device.
