Editorial Review:
Includes USB unit-to-unit cable, Connectivity Cable for other TI units and connection software, operating manual Doing complex calculations on a scientific calculator is much easier with the TI 89. Its large screen offers the ability to generate graphs that can illustrate your conclusions. It's especially helpful with statistic functions, such as regression analysis. The TI-89 Titanium includes all the built in functionality and power of the original TI-89. It has an increased amount of Flash ROM 500KB, quite powerful for a traditional handheld design. This is TI's most sophisticated calculator, with such features as 3D graphing, upgradable flash ROM, built-in assembly language programming, and a generous amount of user-available memory. It now includes a mini USB port. This portable symbolic, numeric, and graphing calculator is perfect for advanced mathematics and engineering applications for college and advanced coursework. Its built-in USB port makes data transfer ultra-convenient. Built-in Flash memory for archiving data(2.7MB) Finance tools, Organizer, Polynomial Root Finder, Simultaneous Equation Solver, and many more apps Fully upgradeable (electronically) through its Flash ROM chip (optional TI Graph-Link required) Computer Algebra System, differential equations, 2D-graphing and data analysis, 3D-graphing with rotations, linear algebra, interactive numeric solver, constants, unit conversions, statistical regressions Optional Assembler language Mathematical expressions appear on the display the same way as they are usually written in class or in published texts and academic journals StudyCards and Symbolic Math Guide for helping students learn more effectively Preloaded with Official AP Calculus exam review questions Built-in USB port for easy data transfer between handhelds - The TI Connect allows rapid data transfer to computers
A good experience.
It's powerful, and has many functions - excellent for linear algebra, symbolic integration even on some improper integrals (the ones with infinite boundaries that converge), Fourier transforms, equation solving of any kind, differential equation solving, symbolic differentiation, complex number arithmetic, number base conversions, etc. For some functions that do not exist, you can download a program in TI BASIC off of many websites or write your own code in C and compile it in TI-GCC, the TI compiler, and put it on the calculator.
User support is the best in the market, because TI is a very popular brand and many people own as their high end handheld calculator either this or the simpler TI-89, with which the Titanium is entirely compatible. Its user manual is decent and provides a good introduction to a beginner. Besides, a simple search on the many support forums will answer any questions.
Like with all handhelds, the bottleneck is generally the user input speed, not the calculator's speed. Nevertheless, this calculator has the slight disadvantage of being rather slow for complex operations which the user can automate, because it's running on a 16 MHz ARM processor. Graphics are very slow for the levels of complexity that my figures require, so I don't even bother with it on the TI 89 Titanium. For those tasks, you're better off using Mathematica or Matlab on your computer. Remember this is a handheld calculator, not some supercomputer.
In summary:
PROS:
1. good user support;
2. many add-on programs available;
3. easy to create your own programs, especially in C;
4. good diversity of pre-installed commands: calculus, linear algebra, spreadsheet capability;
5. large screen (if not largest in this category);
6. easy to master (took me 2 weeks).
CONS:
1. slower than others on the market, like HP 50g, although you might not necessarily notice;
2. lack of a real equation editor - you must type your formulas in on one line, which leads me to lose track of parenthesis matching sometimes.
- Graphing calculator handles calculus, algebra, matrices, and statistical functions
- 188 KB RAM and 2.7 MB flash memory for speed; plenty of storage for functions, programs, data
- Large 100 x 160 pixel display for split-screen views
- USB on-the-go technology for file sharing with other calculators and connecting with PCs
- Backed by 1-year warranty

AS ADVERTISED
Item arrived within days of ordering. Excellent product with an outstanding price. Will buy from this seller again.aaa+++++++ 2008-08-27
Don't believe the list price!!!! Everyone sells it for about $135.00.
I have not found any place that sells this calculator for $199.00. The big discounters were at $130.00 and $135.00. So even if you are willing to pay extra to have it shipped to you, you may be better off getting it at lets say......WalMart, Kmart, Officemax, Staples, or online here used. 2008-08-08
Good calculator
Excellent calculator, and excellent service. The product came as promised.
A good experience.

Great Calculator!
I bought this for my son for college. He is majoring in Computer Electronics and Engineering Technology. The calculator has been very useful to him, both in his beginning classes and as his courses become more advanced. It came with everything he needed to use it right out of the box (batteries, cables, and instruction booklet). And he should continue to be able to use the calculator long after he graduates and moves on into his chosen career field. Good buy! Great product! 2008-07-27
Good symbolic math for a handheld
I'm a grad student in physical chemistry and I use it a lot, both for my symbolic calculations, as well as my numerical ones.
