Review title: Terrible...
Product review: Ridiculously difficult to use. I bought it to use RPN, and 3D graphing, which it does, but for everything else it is a waste. Unless you know someone who knows how to use it and can show you how, don't buy it. The manual is inadequate, the online .pdf is 900 pages and still doesn't tell you how to do simple things, like solve a linear system of equations. Buy a TI-89.
