Great Calculator, But Not For Kids
Originally, I bought the TI-89 for my math classes in High School. This was both a good and bad decision. The TI-89 is indeed a truly amazing calculator. It can figure out most lower level math problems all by
itself. All you do is enter in the entire problem, and it will solve it for...

What you expected to come next from TI.
I have owned 3 TI calculators in my academic life; The TI-85, the TI-86, and the new TI-89. This review will compare them, and give my opinion of the 89.
I bought the TI-89 to replace my broken TI-86, which replaced my stolen TI-85. Compared to both the others, the 89's new interface...

Great calculator - looks less shady than the TI-92
I bought the TI-89 when I went to college. I had owned a TI-92 before, but I thought that the TI-89 (which has basically the same functionality as the 92) would be better considered during tests (as it is approved by the collegeboard, and is of standard size - as opposed to the bulky 92).
