1) Electronics CE Texas Instruments TI-89 Advanced Graphing Calculator by Texas Instruments. I am fairly certain all the glowing reviews of this product are from employees or paid hacks. This thing is a piece of junk, I am curious how much TI pays college professors to force us to buy these difficult to read, poorly documented, over priced hunks of crap. The display is unreadable unless you have a huge light directly over the display even then it sucks, especially compared to the displays available in other small hand held devices, like my iTouch or cell phone. The quality of the documentation is so convoluted and cryptic that it is all but unusable. Don´t waste your money on this if you can get away with using a laptop and excel or other software.¤

2) Electronics CE Texas Instruments TI-89 Advanced Graphing Calculator by Texas Instruments. Having been in engineering classes when the first HP calculator came out that was heavy as a brick and had no "memory", this is an amazing calculator and exactly what my son needed for school. As a matter of fact, he had the choice of renting one for a semester and loved it so much that I got him one for his birthday! He is thrilled.¤

3) Electronics CE Texas Instruments TI-89 Advanced Graphing Calculator by Texas Instruments. This is a great calculator, especially for anyone taking caluculus courses or anything from there on. This has helped me through highschool all the way to college, great product and very reliable. HOWEVER, beware, this is NOT the regular TI-89, this is the Platinum version. I just ordered it thinking I would get the old version because I like the colors and design better (easier to read buttons), and the titanium version arrived yesterday. I dont think it is fair at all, considering I paid extra to get the old version, and from what I´ve seen, I threw away money by thinking that the product description was true... You might as well look for the titanium and buy that, save the extra money...FIVE stars for the calculator, ONE star to amazon for generating all this confusion....¤

4) Electronics CE Texas Instruments TI-89 Advanced Graphing Calculator by Texas Instruments. I bought this like 3-4 years ago and have hardly used it, and it worked great when I needed it, but just recently 1 day suddenly entire rows of pixels started dying on me (literally they started vanishing in front of me). The bottom most row where u enter data is fine, but several rows above it have died. I contacted TI and those thugs ask for 81 bucks for repair or replacement with a reconditioned model. Heck I´d much rather spend 81 bucks and buy some other companies product. Never going back again to TI´s garbage again unless I need it for some course of mine. If I can find some alternate I´ll definitely take that.¤

7) Electronics CE Texas Instruments TI-89 Advanced Graphing Calculator by Texas Instruments. This advanced graphing calculator is packed with more features than you might know how to use. The TI-89 lets you perform the expected functions of an advanced calculator--basic math, algebra, calculus, graphs, matrices, and statistical functions. However, you can also do cool stuff like create animations as well as graph 3-D rotations and plot contours.

The manual that ships with the TI-89 is a killer, presenting over 500 pages of clear, concise definitions, function explanations, examples, drawings, and appendices. It´s divided into well-organized chapters that cover all the major features of the calculator. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing. Additionally, the TI-89 includes symbolic manipulation, constants and measurement units, statistics and data plots, a numeric solver, a text editor, programming capabilities, tables, a split-screen function, variable management, and the ability to link to other calculators or a computer.

The large, color-coded keys are easy to read and find--a nice touch on such a feature-heavy calculator. An improvement over earlier Texas Instruments graphing calculators is the addition of one-touch X, Y, and Z variable keys. The large LCD screen is also adjustable to your environment; we were able to view it clearly in a variety of lighting. The TI-89 comes with an attached, hard slide cover that protects it from getting knocked around in a backpack.

The TI-89´s flash technology allows you to upgrade to future software versions so you don´t have to continually invest in new calculators. The whopping 500 K of memory is more than sufficient for your stored functions, programs, and data. You can also create custom menus or use the default menu. Another cool feature is the Program Editor, which gives you the ability to program. The TI-89 also comes with an input/output port and cable, letting you synch up with other TI-89s or TI-92s. --Jill Lightner

Pros:

• Large keys
• Easy-to-read LCD
• Includes input/output port and cable
• Allowed in AP, SAT, PSAT/NMSQT tests
• Comprehensive, illustrated manual

Cons:

• None

8) Electronics CE Texas Instruments TI-89 Advanced Graphing Calculator by Texas Instruments. Essential for AP Calculus, college math, and beyond, the TI-89 is the most logical handheld technology for advanced mathematics studies. Enhanced with Flash technology, this handheld gives you the flexibility to add calculator software applications and additional functionality, providing long-term value.

Built-in advanced mathematics software includes a Computer Algebra System (CAS) enabling you to manipulate mathematical expressions and functions (factor, solve, differentiate, integrate, and more). It also includes differential equations, 2-D graphing and data analysis, 3-D graphing with rotations, linear algebra, interactive numeric solver, constants, unit conversions, statistical regressions, and optional assembly language programming.¤
