Title: A Quantum Leap in Calculator Technology
Review: Would you use your computer without a mouse? Would you use a PDA without a pen? If so - buy a traditional graphing calculator. If not, buy ClassPad.I have tried to use the CAS features of high end calculators: TI 89, Casio FX 2.0 to solve real algebra problems in my work as a software engineer, but was always frustrated by the difficulty of inputting expressions. The ClassPad solves that, by its natural math input (think Word's Equation Editor).The only small fly in the ointment is the screen display - because of the need to have good battery life (and for someone used to PDA's perpetually running out of juice, ClassPad is excellent in this regard) Casio have not back lit the display, and in low lighting conditions, it can be a little dim. However, removing the protective cover helped enormously, and I'd risk a little eyestrain for the joy of using this little beauty.
