What customers say about "Size & Weight"

Texas Instruments TI-89 Graphing Calculator

It ia not too bulky and easy ta handle.
Smaller, lighter, compact and easy to use.
Calculator easy to use/ I take it at school in my backpack.
I know graphing calculators are big, but wow! It doesn't fit in my pockets, that's for sure! I usually stick it in my backpack or in my cargo pockets on days when I have those kinds of pants.

Texas Instruments TI-Nspire CX Graphing Calculator

This is absolutely what i needed and for the price it is affordable. the right size and easy to use.
I bought it for my middle school child, probably a bit more than what she needs now but plan is for her to get comfortable with keys and functionality ahead of college entry exams.
I understand cutting back on weight a little as the original ti-nspire is a brick to hold, but it fits well in your hand and it feels like it will last me a lifetime.
Smaller, lighter, compact, but not unmanageable for my nimble fingers
Works fine. Used at PSAT. Just wish it was a little more compact in size.

What customers say about "Display"

Texas Instruments TI-89 Graphing Calculator

The screen also has sufficient contrast to use in most lighting conditions.
The only thing that I've never liked is that the letters in the screen are way too little, it takes time to get used to it.
the small text size and lack of a backlight make it extremely difficult to use.
he screen is small though and the text size small; really strains the eyes when working late.

Texas Instruments TI-Nspire CX Graphing Calculator

Easy to use calculator with many great features. The display is very clear and easy to view.
The best graphing calculator ever. You should buy it. Nice color display, nice feature and I'm not kidding.
Bought for my daughter in high school, she was quite impressed with how easy it was to use, and with the color display.
The display is readable. The keys are crisp and the system is intuitive. I give it the geezer seal of approval!
Love the color display and save your work capability.

This calculator is a must have if you are taking a college level calculus course. Taking derivatives is super simple as well as all of the other functions this calculator has to offer.
Easy to use. Updatable and has a lot of free apps.
Calculus is easy for this graphing calculator. It finds derivative, limits and tons of other calculus.
It can graph piecewise functions which is helpful. It can factor and solve quadratics, quartics and higher.
It is a toy because of the lack of speed and memory.
