i have had this calculator now since January '07. i have to admit i am thoroughly satisfied with the service it has provided me. it has been real helpful in my statistics course, although i had to download the application from ti's website. the application is wonderful and easy to use. i use it for my statistics and calculus courses. i use it most in calculus. however, you have to be aware that the calculator is just a calculator and won't solve simple problems the way they are supposed to be solved. although it will find the derivative of a trig function, it does NOT use the chain rule and therefore will give you a wrong answer. i rely on the calculator ONLY to check simple solutions. maybe i had missed something and it will catch it. overall, i am satisfied with the calculator. i like it, and i DISLIKE the ti-83(i've had for years now) and ti-84, although i bought the ti-84 because it was a "requirement" for my stats course. had i known that the ti-89 is easier to use and better for me, i wouldn't have spent [$] on the ti-84 that's just sitting on my desk accumulating dust. i would recommend the ti-89 to anyone because of its ease of use and practical applications.

I bought this after my TI-84+ self destructed the night before am engineering exam. The interface is not intuitive, but there is a lot going on in the background. Honestly, I knew what I needed for my exam, and this calculator wasn't confidence inspiring. It took a bit of relearning to find matrices...

With the stock manual you can muddle through a lot of basic stuff, but the big powerful functions are tricky to find.

The display sucks, period. Tiny pixelated symbols that nearly require a magnifying glass? That's so 1990 (I had one of the first TI-81's, the screen quality hasn't improved by much). I guess I just expect more since I own an iPod Touch...? If I could do it over, I would get a TI-84 again...

        Comments about Texas Instruments TI-89 Graphing Calculator, Titanium:

        This calculator is very nice. I reccomend this a lot when you have to buy the calculator. This has all the funny and exciting functions and options we can press advantage. Differently from others, this can be used for calculus and other mathmtical subjects. I haven't used this a lot yet, but I am expecting them a lot :) Untill now, I've used this for lots of calculations and graphing something! I really recommend you this a lot..Oh, in addition, when you divide something by something, the answer does not come up with decimals, but with fractions. This is very useful when you are middle of process!

        Comments about Texas Instruments TI-89 Graphing Calculator, Titanium:

        I checked several stores for pricing on this particular graphing calculator by Texas Instruments and Staples actually had the best price. I just recently started ordering from Staples, mostly because we don't have one locally and hadn't thought about shopping online, but I'm certainly glad I did! Not only did I save time and gas shopping for this calculator, I was able to have it delivered to my door the very next day. I've been extremely pleased with all the items I've ordered from Staples.

        My daughter loves her new TI-89 calculator. She opted for this model because she is studying engineering in college next year. Makes doing her high school calculus and stats homework easier.
