Digital camera reviews of Texas Instruments TI-89 Advanced Graphing Calculator

This calculator is amazing it's almost cheating especially in lower (relitivly :)) level math classes (high school algebra 1/2, intro trig etc.)Digital camera Review: An asset even after college.
Summary: 5 Stars
I purchased my TI-89 two years ago, and the durability, along with upgradability will make me a repeat customer for life! I started almost 10 years ago with the TI-81, which was I believe the first graphing calculator available for regular consumer use. What power in that time! I have dropped my calculator, stepped on it, and no stratches or errors. It truly behaves brand new. Not to mention the ability to do differential equations, slope fields, and download virtually any program you could want. The battle between HPers and TI faithfuls go on, but my loyalty will always be TI. The fact you don't need some module to use programs, the display, and the option that if you truly want an HP interface, [web site] will allow you to download an application for that for free! With the exception of a few programs, that are well worth the cost, you could download any program for free, and expand this already boundryless calculator. Even after college, this calc proves to be useful for engineers that aren't near a computer. I recommend this over HP to anyone!Digital camera Review: Awesome
Summary: 5 Stars
It does everything I need and more. Great for people who are taking a Calculus class.Digital camera Review: Awesome isn't the word for this calculator!
Summary: 5 Stars
This calculator is so awesome. Not only does it do integrals, derivatives, Taylor Series, matrix functions, etc....but it does it in a format that looks like what you would write down on your paper. Oh, I forgot to mention, it also does limits!!! This calculator is a must for any engineering student! It is a lot to pay at one time, but it is so upgradable that you will never need to buy another calculator again!Digital camera Review: Best Calculator EVER.
Summary: 5 Stars
I almost exploded in laughter when I opened the packaging on this calculator. The enclosed manual was thicker than the one for my car! Not only that, but when I read about and tried the solve and factor functions, I was never more amazed. The best thing is, that you can punch in a problem like 4(37x+93)^2=24 and it will solve it in a manner of seconds, much quicker than I could ever hope to solve a problem. (not like that one's particullary difficult, mind, I'm only using it as an example) I will say that the only difficulty with this calculator is that programs written in the *.89p format are not compatable with any other model, so I am unable to share games or apps with friends. This calc's pros completly mask it's cons.
