I agree with a previous response that engineering costs money, but these products have remained virtually unchanged over nearly 20 years, with the vast majority of expenses having been amortized long ago. I worked for TI once upon a time, I suspect they have no more than a couple of engineers (across hardware and software) actively maintaining these products. Comparing the latest TI-84+ CE at $149 with a current iPod at $199 there is an order of magnitude more technology in the iPod.The reason TI is able to maintain pricing on this product is because theyu2019ve essentially built themselves a monopoly position in the educational graphing calculator market segment. Yes, there are other (arguably better) products from Casio, HP, and others, but TI has invested enough resources in supporting teachers and students in the use of this line of calculators that they enjoy something approaching 90% market share, and few individual schools or districts would find it worthwhile to invest in training teachers on using a less expensive product. I imagine weu2019ll see a steady transition from dedicated calculators to much less expensive apps on tablets or laptops, but given the unique acceptance of graphing calculators while taking standardized tests, there is a pretty good moat in place protecting the market.While itu2019s maddening to pay 10x for a product which would appear to cost a tiny fraction of that to manufacture and sell, good for TI in building this market niche, especially without benefit of most of the regulations which distort market pricing for pharmaceuticals and many other products.
