It's a good product that will last a long time yet. You grab it out of a drawer and use it and put it back. It doesn't require any maintenance past some batteries changing occasionally. And it has buttons, real ones.
It's rarely about power either. Very little in mathematics requires much computational power other than a few joules between your ears. Then you're going to use a computer or CAS anyway.
- Chinjut 12y agoApart from having real buttons, I don't see how that doesn't apply to people's phones just as well. Nonetheless, I agree that the TI-89 is a great product. It's also a 16 years old piece of electronics; there's no good reason for it to be as pricy as it is. And the value proposition for the TI graphing calculators which lack CAS abilities is even far worse. The pricing does not seem to reflect a truly competitive market.
