 TI could have done better May 30, 2008
0 out of 2 found this review helpful
I used a TI-81 back in 1993 in college and have been using TI calculators ever since. I especially like the TI-89 and Voyage 200. When I found out TI had come out with a newly-designed model with CAS (Computer Algebra System) capabilities I was eager to start using it.
Having used the calculator I have to say I am dissapointed. The green letter keys are WAY to close to the number keys. I am constantly having to correct simple numerical inputs that come out like "4p5km31t". TI should include a feature on an updated operating system that allows a user to "lock" alpha keys so that they won't muddy up inputs if they are accidentally pressed. The keys are very sensitive so even if you lightly press them you will have to make corrections.
The screen's resolution is a little dim. TI should have included a tilt-screen so people wouldn't have to raise the whole clunky calculator up to see results of a calcuation.
The features on this calculator probably work best with the computer software version of nSpire.
Great Potential - Needs Work April 26, 2008

I've been working with this calculator for more than two months. My advice? Wait! Wait for updates and upgrades. First, I have to agree with another reviewer who was so angry with the documentation: it's awful. Harks back to the early 1980s when the only way to know what a computer could do was to try it. Trying to figure out how to do even the simplest of operations sometimes required an hour's worth of searching, at times with no resolution. The most helpful thing I've done so far is to print out the entire function manual and read through it page by page, but even this won't help you with specific button operations. Also, if I call technical support and they say they'll have to call me back, I expect to be called back. I don't expect to never hear from them again. Very, very annoying. Lacks class and corporate integrity.
I'm also unhappy with the screen. Although it has excellent resolution, it is very difficult to see unless the ambient light is bright, if not you have to tilt it at just the right angle to see anything. I don't know if it's technologically possible, but backlighting might help significantly. Also, they might want to work on providing 3D graphics.
There are also some operating system tweaks they need to make. For example, in the calculator mode Tab key will move you to the next part of the expression, but in graphing mode it appears to function the same as the Enter key and prematurely enters the expression.
There is also an operating system bug. It appears that if you "grab" something and you allow the calculator to auto power down it locks up. Doing a "soft reset" by pressing the button on the back will not unlock the system. You have to do a "hard reset" by removing a battery.
So what do I like? Almost everything else. I love the wysiwyg interface! It's as if you could actually do calculations with the MS equation editor. I haven't had a problem using the buttons. Also, the calculator is incredible powerful, there are a huge range of functions and operations. Final word: wait for them to solve the problems I've outlined above and then buy one.
 Amazing Calculator!!! April 25, 2008

I have always been required to have a Texas Instruments calculator for school and have upgraded many times since elementary school. I am now a freshmen in college and upgraded my TI-89 Titanium to this TI-Nspire CAS which technically has not been released publically yet, it will Fall 2008 though. I was so impressed, I thought the 89 processed equations fast, this one blows it out of the water. Another really cool part is that you can see the graph, equation, and table all on the same screen. This model of the Nspire (CAS), also will solve quadratic functions (solve for x) which seems to be really handy on test days because it shaves about 3 minutes off per chemistry problem for me. The other nice feature is the improved screen resolution as well. One last thing to note is that it is slightly larger than the other TI graphing calculators, which is a concern to some. In conclusion, this does everything a TI-89 does and them some. If you want the best TI has, I think this is it!!!

Poor user Manual, should have just included a reference manual of all the functions on the calculator.
The screen is not as sharp as advertised. Its blurry in low light conditions.
Other than that, its a very, very functional scientific calculator.
Great calculator! March 20, 2008

^_^. I absolutely adore this calculator. I upgraded to this from my TI-92+ that had since 2000. >.<
