Cons: Expensive. Classmates asking me to play games on it...during class. Slackers...

*Note: This review pertains to the TI-89 Titanium, which is newer than the regular TI89.* What a calculator! In middle school math, I had a scientific calculator. Back then, scientific calculators seemed like the most advanced calculators out ...

Pros: Powerful math capabilities, lots of storage space
Cons: Tricky to use, a little unintuitive

For three years of high school math (precalculus, calculus, and linear algebra), I happily used my school-issued TI-83 plus. It was perfect for precalculus, and it was useful for calculus, too, but by senior year I was taking multivariable calculus, and...

Pros: Very powerful, 3-D graphing capabilities, easy-to-use drop down menus
Cons: Steep learning curve, difficult to learn the interface coming from other TI calculators, expensive

As a sophomore, my high school splurged and purchased TI-92 graphing calculators for the lot of us. While coming from a TI-83 background made it difficult to use the new interface, I was amazed at the power. Solving algebraic equations, factoring, ...

Pros: Fantastic Functionality, Ease of Use once Learned
Cons: A Little Hard to Learn, Pricey

I upgraded from my TI-83 to my 89 as a Sophomore in High School. I now keep it with me at work, and have used it in many different academic and professional situations. IT is an incredibly powerful tool, and I'll try to tell you why I'm so happy with ...

Pros: powerful functions, expandability, easy to use.
Cons: small screen, pricey.

Lets face it: we live in a technological age. I am extremely reliant on my calculator, and most math classes nowadays are intensively calculator based. I agree that it is somewhat pathetic. I cannot image how people took calculus and other high level ...

Pros: Calculus, Downloadable Flash Apps, pretty print, Powerful calculator
Cons: slightly expensive, not a very good owner's manual

Overview
The TI-89 is a great all around calculator from TI. This calculator can be used for chemists, physicists, mathematicians, engineers, and many more. This calculator has many functions and is very expandable.

Who should...

Pros: Fast, versatile, capacious for a calculator. Presently the extreme high end of performance.
Cons: Learning curve. Teachers don't like the gaming and cheating possibilities.

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 ...

Pros: Rampant, motley and sometimes muddled power
Cons: NOT really a calculator but a computer with calculator applications, and it shows!

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 ...
