Rating:  - Texas Instruments TI-89 Titanium Graphing CalculatorThe TI-89 Titanium Graphing calculator is the best calculator I've ever owned and used. I switched from my HP-48 GX in 2003 and never had any regrets! The TI-89 Titanium has + and - when it is compared to the HP-48GX. For instance, the display on the TI-89 doesn't appear as big as on the HP-48 GX ( a slight minus (-)). However, this slight inconvenience, is greatly outweighed with the overall calculator ability of the TI-89 Titanium. The calcululator can effortlessly solve integrals, triple integrals, vectors, you name it. The screen display also lets you check to see that the equation or expression you're evaluating is actually what you desire. ((BIG PLUS ++). I highly recommend this calculator to anyone who wants the defacto "most powerful calculator in the world". JML Rating: - It's better than we expected with excellent delivery service.I purchased the product for my son and he is thrilled with it. It's cut down his home work time and increased his accuracy. Rating:  - The Potential Was There but TI Didn't DeliverAfter having used the TI-89 Titanium for a couple of years, I have discarded it for the older HP48GX. I have found that I prefer the Reverse Polish input of method of the HP but the TI-89 has a number of other problems. 1) Yes, it is a very powerful machine. However, Texas Instruments did not see fit to provide an Equation Writer: attempting to input complex equations on the Command Line is a real PITA. Once you get the equation input, you will see it displayed in "Pretty Print" which means that it now looks like a written equation but you can't do that in the first place. 2) The TI-89 Ti is not programmed out of the box to handle vectors. The target market has to include a lot of engineering students that would like that feature. The HP48GX on the other hand, with a push of a button can give me the dot product, cross product, magnitude, etc, etc. 3) Without an Equation Writer, the syntax to get differentials, integrals, etc takes some getting used to. 4) The manual supplied with the calculator is terse to the point of being cryptic in showing how to input more advanced mathematical techniques. However, that seems to be an industry wide problem because of the costs of producing and printing paper manuals. 5) The contrast with the silver gray background and the blue and yellow lettering for the secondary and tertiary functions is poor. Additionally, the letters are very small and difficult to see in the first place. 6) The contrast of the screen sucks! If you're the wrong side of 40 and wearing bifocals, good luck in trying to read a dialog box. TI should have also provided a magnifying glass. Over-all, this is a very powerful calculator and some of the problems can be corrected with add-on programs. But...my decade-old HP48GX has features that TI did not see fit to put on a more "modern" machine. The TI-89 Ti has the horsepower but it is not harnessed effectively. Rating:  - Awesome Calculator! Exactly what i neededi ordered the TI-89 for my calculus classes in college. I wasn't thrilled by the price, but it has turned out to be money well spent. i absolutely love the features that the TI-89 comes with. Excellent buy! Rating: - works great! a little confusing thoughdoes everything a calculus student needs it to do! a little complicated to use but comes with a bible of an instruction booklet Texas Instruments TI-89 Titanium Graphing Calculator ReviewsMore reviews:Buy Texas Instruments TI-89 Titanium Graphing Calculator Sale Reviews Deals
