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.
