This calculator is a must for any Calculus AB class or above. It is the first in the TI series that handles integrals, differentials, 3D graphing, differential equations, user-defined variables, upper and lowercase lettering, and custom flash apps... to name a few. It has a visually-pleasing home screen, to allow you to see equations as they would naturally be written, instead of in a single line filled with parenthesis. Built-in flash applications allow you to do things like create study cards, edit lists and matrices, edit text, and solve simultaneous equations. The one con about this calculator is that it is much less adept at performing statistical operations, such as linear regression, than the previous TI calculators. The TI-89 Titanium, however, was designed for calculus, so this is not a huge problem.
The buttons are very quiet and responsive. Over time, depending on what they are expose to, then can become occasionally stuck, but anyone who treats this calculator well won't have any trouble with the input. Using this calculator for about 4 hours a week, a fresh set of four Duracell batteries lasted 6 months in the device. This will vary depending on your contrast settings. The case is quite durable, but that's not to say that the components are, so be careful with this.
This is a top-choice calculator for any level Calculus class, and I would recommend it to anyone.

Amazon.com Product Description:Amazon.com Product Description This advanced graphing calculator is packed with more features than you might know how to use. The TI-89 Titanium lets you perform the expected functions of an advanced model--basic math, algebra, calculus, graphs, matrices, and statistical functions--and do cool stuff like creating animations, graphing 3-D rotations, and plotting contours. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing. Additionally, the TI-89 Titanium 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 TI-89 Titanium's flash technology allows you to upgrade to future software versions without having to continually invest in new calculators. The 188 KB of RAM, combined with an impressive 2.7 MB of flash memory (three times the memory of the TI-89), are more than sufficient for your stored functions, programs, and data, and add welcome speed to go with the TI's reliability. You can create custom menus or use the default menu. Another cool feature is the Program Editor, which gives you the ability to write custom applications.
The large LCD is adjustable to your environment and can be viewed clearly under a variety of lighting conditions. The calculator also comes with an input/output port and cable, letting you synch up with other TI-89s or TI-92s, as well as a USB port and cable. An attached, hard slide cover protects the calculator from getting knocked around in your backpack. The manual that ships with the TI-89 Titanium 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.

Calculus and beyond.
I'm a master of the TI-83 calculator, and can do just about anything on it. I'm taking calculus courses in college, however, and the TI-83 doesn't support much mathematics past algebra.
First off, this thing kicks ass if you just need to know something without all the steps in between. It's very easy to factor, differentiate, anti-differentiate, solve equations, etc.
My only major con is the learning curve involved with this calculator may be a little steep. Being in a college course, I have to show my steps in solving problems. This calculator won't do that for me, but it allows me to double check my answers.

I really love this calculator...Once you learn how to use it. Seriously this calculator is pretty unreasonable to use until you read a detailed manual (and not the one TI gives you...that thing is junk). I highly recommend you pick up the idiot's guide or something along those lines to get the most out of this calculator. After a weekend of reading the idiot's manual I was good to go. Once you learn how to input formulas and commands properly in this calculator then it's downhill running from there. The TI89 is super powerful and simple to use once you get use to it. I rarely use another calculator permitting on the exam. It comes with strong financial, mathematical, and statistical functions that is great for undergrad classes. It also has loads of option even down to how you want you're decimals rounded and various other picky mathematical settings.
My only complaint with this calculator is that the case is made out of some cheap plastic. My case is all cracked, scratched, and dinged up. I take care of this calculator and have never dropped it. This plastic just wears down really quickly. I'll be needing a new case soon at this rate.
Back to school bargain
Buying these slightly used calculators on Amazon is something that colleges tudents need to know about..price savings are substantial and well worth it
