Bests & Worsts Reviews from Amazon

The actual calculator itself is stunningly powerful. It is faster than the TI-92, the full keyboard makes it easier to work with than the TI-89, and the ability to solve, factor, work with imaginary numbers, give exact answers, as well as do all of these things symbolically, plus the amazing applications included (a version of Geometer's sketchpad!), make this the best calculator made by TI. Just beware that some standardized tests and some teachers will not let you use this calculator. The biggest drawback is the documentation that is supposed to help you utilize the power of this calculator. There really isn't any. There's a short manual that's included in the box, but it only gives you the broad overview of how to put the batteries in and how to turn it on and off. To find any information on how to, say, type something in that you want to factor, you have to load up the cd-rom, and hunt around on that thing to find the information you want. Why don't they include all of this documentation along with the calculator in an actual book form? (Okay, so I know the answer to that - it saves money for them.) It's a huge hassle - if I'm at class, or work and want to be able to use some function, I have to wait to figure it out until I can get home and load up the cd-rom, find the right page, etc....not to mention that the documentation on the CD-rom isn't that helpful either. There's lots of discussion of stuff, but it is very hard to understand. A great calculator, but awful documentation that makes learning how to use all of its powerful functions frustrating and annoying.
