Ti-89 has had a monopoly on the calculator market for a very long time, and it shows in their lack of new developments or price decrease.
if you think about the technology that is inside them as compared to todays standards of growth.

Plus the fact that the ipod touch can do 80 billion other things. Now, granted that a lot of what you are paying for in the ti-89 is the software of the calculations, but those calculations and programs really haven't changed that much in the last 15 or so years.
Yet, I still have to buy a ti-89 as fear of using an ipod touch or phone to cheat. I still don't appreciate being gouged.
What's great about it: You have to have it for high end math based classes, no ifs ands or buts.
What's not so great: were are paying for much much outdated technology.
No, I would not recommend this to a friend.

I bought this to replace an older model TI-89 that was no longer working. I use this for Calculus and Physics. It has some different features from the older TI-89, but I was able to use it for my purposes straight out of the package without having to look at the manual. I do think that these things are a bit overpriced. I was also not crazy about the curved layout of the keypad, but I am getting used to it. I do not like the home screen, and I think that after all these years, the screen quality could have been improved. I like the calculator, but I am rather unimpressed. I would never have upgraded if my old one had still been functional. I just needed a graphing calculator that could do integrals.
What's great about it: Easy to use, good for Calc 1-3 and Physics, can calculate integrals
What's not so great: Cover is hard to get on/off, screen could be better, curved keypad layout is odd, overpriced
I would recommend this to a friend!

I purchased this for a class I'm taking and it really simplifies solving equations. Has a lot of capabilities that were not available a few years ago.
What's great about it: Solves simultaneous equations
What's not so great: Screen is hard to read

This is an amazing calculator that is capable of performing most advanced calculations. Can be used in conjunction with an optional USB cable in order to upload data points and programs. This has same functionality as TI-92 minus the full keyboard. I had no problem using this calculator on test or exams, but I would recommend checking with your Professor/Teacher prior to purchasing.
What's great about it: Quickly calculates advanced calculations
I would recommend this to a friend!

I purchased this after giving my TI-83 to a sibling. This calculator is light years ahead of the 83. The screen is sharper, there's more memory for storing programs, and there are many more functions than my old graphing calculator.
The TI-89 has helped me so much with my college calculus & physics courses. Texas Instruments has really outdone themselves with this.
What's great about it: everything
What's not so great: none

Great aid for those taking higher math courses. Takes I believe 4 double a batteries which last quite long. The screen is large enough for easy viewing and once you get used to the calculator, you will know it by nature and will become a powerful tool.
I would recommend this to a friend!

I received this product summer of 2005. The capabilities of this product is seemingly endless! When it comes to math, this calculator far exceeds the capabilities of my old TI83+. It can solve your calculus problems in a jiffy, and it has the ability to do enough math functions to satisfy a high school or college student. If there is anything lacking, there are websites where users can upload calculator programs and games. The battery life on this is simply amazing, I recharge my batteries perhaps once a year. Now that I am no longer taking math, I use still use my TI89T as a calendar, and note taker. It also stores all of my phone numbers, which came in handy when I switched cell phones. In other words, this calculator can do almost anything you want it to do!
What's great about it: many free programs, math capabilities
What's not so great: none!
I would recommend this to a friend!

The price should keep most people just looking to add and subtract away, but if you're in calculus, this is the one for you!!
Features FAR beyond the TI-84+, and better screen resolution and battery life. I used this one for three years in college. GREAT calc! Good investment for students, I still use mine!
What's great about it: Features
What's not so great: not nec. for all users
