And why Casion not makes a clone of TI-84 ?? Same layout of keys, same programming language.
In any case. I never had a graphing calculator. I was happy with the typical cheap Casio calculator. The last calculator that I bought, when I was on school, is an old fx-85WA and it keeps working perfectly. For doing some quick calcs works perfectly, and if I need something more powerful, I simple open a python console or gnuplot on my computer.
I never saw that a teacher enforce us to use a particular kind of calculator, except the prohibition of using a programmable calculator for exams.
- rgawdzik 12y agoIt's against the law?
- loup-vaillant 12y agoMaybe. Some parts of the design may be copyrighted. I think the programming language cannot be, and patents, if any, have probably expired by now. The problem then is, once you have the clone, you need to get the professors to know about it, and not requiring any specific calculator. In any case, I'm not sure it would change much in practice. When I was at school, teachers didn't require any particular calculator. Half my class chose Casio, the other Ti. Two competitors are apparently not enough to drive prices down.

- loup-vaillant 12y agoCopyright never expires: it gets extended faster than time itself.
