why are TI graphing calculators still so expensive

[Don Shepherd]

Thanks Lionel, good observations.

In my closet I have 4 TI-83's for use by my students, 1 TI-84 Plus Silver Edition that got me through education school about 10 years ago, 1 TI-89 Titanium, and 1 TI-Nspire CAS (monochrome, not the latest edition obviously). The 89 and Nspire, while powerful, are maddening because they are non-intuitive; I can never remember how to accomplish even simple things on them, therefore I almost never use them. The 83's and 84's are familiar machines, so they get used.

I have left the Windows PC world for the Chromebook world and am very happy there.
