Texas Instruments - Graphic Calculator

The graphing faceplate is compatible with a TI 84 plus so can be used in school as always. The Nspire faceplate utilizes a complete geometry program equal to a computer. Much to learn but is much more versatile.

I just bought this for my son since he needed a TI-84 figuring he could start with that keypad and grow into the Nspire keypad. I don't know enough about it to rate the features, etc so I left that blank. What I did discover though is that in order to back up data entered in TI-84 mode, you need to purchase a separate cable. The USB cable that comes with it will only work properly with the Nspire keypad. The handbook tells you you need to back up TI-84 data before updating the OS or you'll lose it and also tells you that you need a different cable to back up TI-84 data. However, that cable was not in the package and when I called to ask about it, I was told it wasn't included but could be ordered. I made enough noise that they're sending me one for free but I shouldn't have had to do that. They advertise the fact that it can be used as a TI-84, they should provide the cable to backup the data. I would only buy this if I already had a TI-84 at home since you can use the same cable.

The Ti-nspire is the best Ti calculator I own . I have the Ti-89, and the Ti-84 plus silver. If your planning to buy a new Ti calculator then the Ti-nspire would be the best option. It has a slight learning curve, but well worth the time.
