TI-89 vs HP49G+
Posted by Michael on 22 January 2004, 02:46 GMT

Al Borowski has created a webpage comparing the differences between the TI-89 and the HP 49G+, two calculators in their respective company's high-end model line. This is still a work in progress, and there's also a mirror because apparently we are thought to have some sort of slashdot-like server crashing power - I'm not sure about that :)

IMO, ti and hp are aiming at different markets. As you probably know, ti aims at eduaction (education.ti.com) and hp is more for professionals. The problem for hp is that people who had to by a ti in high school usually continue to use ti's. I am the only guy at my high school with an hp49g+. It is harder to learn than the 89, but the rpn and the sd card are indispensable (the sound is nice too). One thing which the review didn't address was the keyboards on the calculators. The hp has a very stiff keyboard, which took a lot of getting used to. The keyboard is not perfect, some of the earlier production 49g+'s have defective keys which do not always register, but mine is perfect. The 89 keyboard is much softer and mushier.

It's really too bad that TI only aims at education-if they made some changes to the 86, 89, and 92, they would be great for professional work.

I have a Hp49G+ in high school and I have found out that you learn alot better how to use your machine when you are not told how to do functions and are forced to learn them on your own and also no one ever asks to use your calculator!

Ti's may be easier to use at first but the Hp's can do alot more

I total agree with you that TI and HP aim at different markets. TI model bases on matching, perfect world; while HP model bases on real world (circuit analysis). that why for symbolic integration "the Hp still cannot compare to the speed
of the Ti’s, since a calculation cannot compete with a table. Often, real world problems
have no pretty answers and that is why Hp chose to use a slower algorithm approach; not
nearly as fast or pretty, but this can be more effective and with the added caveat of a step
by step solution"(Ron Ross, 2005).
As for layout of keyboard, I don't think TI 89titanium be good. one example, it does't have "log" button. For engineering student, it is a very important button, how can? My opinion, for engineering students at a university, HP 49g+ would be much better, although TI 89 is good too. As for high school, TI would be their choise.
