My Math Buddy
I (actually, my dad) purchased my TI-89 in the September of 1999 for my math classes in high school. It was very expensive - $149.99 - and my dad wasn't too thrilled about the price. But in my experience, the TI-89 was a very good purchase. I've used it in all my math and science classes so far and... Read full review »
Math Students Dream
The TI89 is almost definitely the best calculator available today. It contains all the advantages of the TI 92 but in a hand held form. Set up in a windows-like fashion, this calculator is very easy to figure out: For example, if you want to use a calculus function, you just scroll to the calculus... Read full review »
the best ever
Like the title says this is the best calculator ever. I just bought this 2 weeks ago. While doing my research I had read a lot of reviews saying that the [2nd],[ALPHA], and the diamond button functions were hard to read . Do not believe the people that wrote that, they are either near blind or are... Read full review »
A Powerful Math Machine, many interesting Functions
The Ti-89 is a fantastic calculator and very easy to use if you bother to sit down and read the manual. If you don't read the manual, then you wont know what to do. You have to take time and then you will know how to operate this machine and utilize all of its features easily.

The TI-89 Titanium is a first-class toy!
I never really had a graphing calculator before, and I wanted to get a good one. Everybody who had something to say on the subject said that the TI-89 Titanium was the best in the class. So I went on eBay and bought one for $110 plus $8 shipping.
The prices have been coming down since I made...

A Revolutionary Tool for the Average Student
A machine capable of doing calculations, equations, and functions that would boggle the human brain, while being able to play games such as Super Mario. This is the TI-89. The TI-89 is a step down from the TI-92 and TI-92 plus, but it still packs a punch. While being able to do differential... Read full review »
Everything you could want, and more!
As a newly enrolled Calculus student, It was recommended to me by one of my professors that I purchase this calculator. After some grumbling over the high price ($150-$170), I relented and bought this calculator and haven't regretted it. Not only is everything you NEED for calculus, it is... Read full review »
TI-89 Titanium: Great for science and engineering students
I'm a longtime TI user: I had a TI-83+ in high school, then moved up to a TI-86, which I then used in college. After college, these both got occasional use for a few years until I decided to change careers, and returned to school to study engineering. Then I pulled out the 86, which worked for...

TI-89 Titanium- arrrgh!!!!
Having been an electronics engineer for 20 years, I use calculators quite a bit. I decided it was time to replace my dozen year-old HP 28S with the biggest, baddest TI available. Now, I'm thinking that was a mistake. The features on this calculator are very poorly integrated. TI seems to have taken... Read full review »
