Why Do Ancient Graphing Calculators Still Cost So Much?

Ah esta é engraçada.... admira-me (ou não) que os responsáveis pela Educação em Portugal e noutros países não saibam nada do que se está a passar.

Spotted in Best Buy over the weekend. Twenty feet away, iPod Touches were on sale for $200. There's no way this makes sense.

(...) students are effectively forced to buy these products, and TI is discouraged from innovating in any real way. The calculator industry is not unlike the textbook industry: normal economics do not apply here. Students — or really, parents — are stuck with these things, and their prices, until CollegeBoard and teachers either figure out how to trust their students to use multi-purpose devices or TI brings its prices down. But why would they do that? This is easy money.
