Texas Instruments TI-89

The TI-89 is a popular graphing calculator made by Texas Instruments, originally released in 1998. It features powerful computer algebra system (CAS) that can solve albebraic expressions in symbolic terms; most other calculators solve in terms of number only.  For example, entering (x^3-x^2-8x+12)/(x+3) returns x2 − 4x + 4, which is pretty printed by default. The current version of the calculator that is sold in stores is the TI-89 Titanium model, released in 2004 to replace the popular original TI-89. In the United States, the TI-89 is allowed by the College Board on all calculator-permitted tests, including the SAT, however it is banned from some other tests and classrooms because of it's advanced function. The retail price of this calculator is $150.

TI-89 Titanium

The TI-89 Titanium was relased in the summer of 2004 as a replacement to the popular original TI-89 calculator. It expands the available amount of flash memory to four times of its predecessor, adds a mini-USB port for connectivity with a PC, other TI-89 calculators, or other calculator accessories including a full-size keyboard.

Case Swapping

It very common for students, in an effort to curtail their school's calculator restrictons, is to remove the internal components of the TI-89 and put in in the TI-83+ shell. There also have been students doing the reverse (ie. putting the TI-83 components inside the TI-89 shell) and selling the subsequent calculator as a true TI-89 and profitting in the process.

The TI-89 Titanium looks to be a good calculator. I have been doing my homework and it appears to be one of the flag ships for TI. The calculator has many of the features of the rest of TI's calculators like solvers, graphing, etc. But it does have a statistics package that is unique and it can solve differential equations. I looked for some good pictures and found them here: TI-89 Titanium

Bottom line it seems this is the best buy if you are planning on college math.

It's great for any math, Algebra and up. It makes getting through busy work much quicker, and TI-BASIC is easy to learn, so it's easy to make programs to do equations and other stuff for you. And if you're clever enough, you can even get them to show work.
