why are TI graphing calculators still so expensive

[damaltor]

Well, my trusty old 83+SE brought me through my degrees. The answer is, at least for me, simple: because they are friggin good calculators!

Seriously, TI calculators are well-made machines with good algorithms and also usually very good usuability. The fact that you can put games on them is funny, too - but no exclusive to TI.

If you are searching for a good, fast and reliable (though huge) calculator from TI, go for the TI-92 plus - they usually sell cheap. i bought mine for 10 bucks.
