Over the past year, I've used two different graphing calculators - the TI Nspire and the ClassPad 300. I started with the TI and, while it does a lot and appears to be well designed, the documentation is absolutely horrible and the calculator is also not intuitive. I spent many months trying to learn how to use it and finally gave up. It was at that time that I decided to try the ClassPad and found that I liked it a lot more than the TI. In fact, I'm very sorry I didn't try the ClassPad first.
In comparison to the TI, the ClassPad is far more intuitive, I love the touch screen - especially because it makes entering complex equations much easier than using the key pad, and the learning curve is significantly less than that of the TI (again, I finally gave up on the TI after trying for months to understand it).
Although the ClassPad is a great calculator, I wish that the screen had a backlight and that there was more, a lot more, documentation. I also disliked the small icons that appear on the touch screen and wish that there was some way to identify what each means without having to search for them in the manual.
Overall, this is a far better and more intuitive calculator and would highly recommend this over the TI any day.Get more detail about Casio ClassPad 300 Touch-Screen Graphing Scientific Calculator.
