Texas Instruments TI-NSpire Math and Science Handheld Graphing Calculator(Swap Keypad)

Pros: Decent scientific calculator.

Cons: No official programmability.

Other Thoughts: This is $20 cheaper on that other online retailer whose name is that of a large river basin in South America (Ama-zon). Really, Newegg, competitors' names are inappropriate?

Pros: • Well, it's a TI calculator, so it runs quite well and is well supported
• Has lots of features, the pretty print being a great one
• Graph manipulation is unmatched
• Much faster than a TI-83+/84+ grade calculator

Cons: • Poor programming support
• Locked CAS functions are still present, but unusable
• TI-84 keypad is chunky and has an annoying d-pad layout
• TI-84 emulation is imperfect, breaking MirageOS without a messy patch

Other Thoughts: If you have a TI-84+ (Silver or not) don't buy this. You can get nearly everything this does with OmniCalc and Symbolic. If you're buying your first TI graphing calculator, however, this is the one to get. It's compatibility with the 84, while slightly buggy, gets the job done quite well. The only thing you must consider, above all else, is that programming support for the Nspire side is awful. I expected to have some serious power behind my programs, and was astounded to find that TI doesn't even have a way to run Assembly style programs on this device. It seems like a step back from the 83+/84+ to take that away. Other than that, this is a well built calculator for the stock functions it includes. Just don't expect to do much else with it than what it already can do out of the box.

Pros: Has a high-resolution screen, which looks awesome. The drag-and-drop/pretty print features work, though are a bit gimmicky. Swappable keypads are a feature I have come to appreciate, and it works flawlessly.

Cons: :::Programming is little to nonexistent; it can't even accept variables mid-program. This means no home-made games.

:::Graphs look nice, but actually finding usable information from them is a hassle. I have read the entire manual and cant even figure out how to find intercepts or zeros.

:::Pretty print works, though it ends up taking more time to find a 'log' or summation than it would on the 84/89. You have to scroll/tab your way through all the little entry boxes instead of just hitting a couple buttons.

:::There are several functions which have keys, and yet prompt you to purchase the nSpire CAS when you utilize them. For example, Summation Notation, Limits, and the "Solve" feature. Why even include these in the OS if you cant use them?

:::Every once in a while, it will take 10-15 seconds to boot up after hitting the power. My chemistry teacher jokes that my "computer" is booting up when this happens.

:::This machine is MASSIVE; pocketable, but just barely.

Other Thoughts: cI honestly find myself using my ~$20 TI-30xIIs more than this, because of it's small size and adequate feature set. Unfortunately, I will need more power come Calculus, so I think I will sell my nSpire for a TI-89.

In short, I DO NOT recommend this product. For up to grade 10, a TI-30 should be completely adequate. If you are going into a field like engineering or science/math, than just splurge and get a TI-89 right now. If not, than just go for a TI-84. It's got the power, and most schools use them anyway.

Pros: You have all the functions u need...

Cons: keys are somewhat small, the learning curve is somewhat steep.....

Other Thoughts: okay product i guess but i would wait for the next version next time

Pros: Its basically a really good ti-84plus

Cons: none

Other Thoughts: I would rather use the ti-89

Pros: great interface, easy to navigate, ti-84 capability is cool, this is like the new Ti-84 plus silver, i love it, lots of memory

Cons: Not a touchscreen, they make it out to sound like it is but it isnt, no backup battery

Other Thoughts: dont buy the CAS one is u got to school
