    Call me totally impressed! I have used the TI-83/84 calculators for years but rarely the advanced features they offered. I often found them to obscure and annoying. The Nspire takes a powerful document approach that is totally different than the Ti 83/84 series.

    This Nspire CAS Touchpad is quite a revelation. It took me all of an hour to understand (with the Dummies book at my side) almost all the functions it offers. The keypad is clear and obvious unlike the first versions of the Nspire. I was amazed at how much I could do with this device with so little effort. I have been using Mathematica for many of the classes I teach. The Nspire can replace Mathematica for most of the things we do in undergraduate physics and engineering courses. That is impressive.

    The large screen is a bonus. The characters are clear with high resolution. The large screen means that everything you do is easier to see and analyze. The screen is adjustable but it is still a calculator screen. You need light to see it well as it is not backlit like LCD computer monitors.

    Some people compare the Nspire with the Ti-89. Sorry, no contest. This Inspire runs rings around the Ti-89, a calculator I never really liked. It is faster, easier to use and read, and a joy to use. Don't waste your time with the TI-89. Putting a little time in learning the Nspire paradigm will reward you.

    The Nspire comes with desktop software that duplicates the functions of the calculator. On a MacBook Pro, it installed right away without problems. There is a link included with the software that allows you to backup and update the Nspire as well as move files back and forth.

    The Nspire links up with the Venier Go! and EasyLink sensors. I haven't tried this yet but will in the next week or so.

    I'm in the process of trying to learn about ballistics. Although I am a computer programmer by trade, I wanted a more portable graphing solution for some of the rather complicated equations involved in long range target ballistics.

    I first bought a TI-89 Platinum calculator - worked nicely, the UI was relatively intuitive, but it was fairly slow. So I started looking at HP and upscale TI graphing calculators. The TI Nspire seemed a good fit so I bought a regular one at a local office supply store. Unfortunately, the model I bought lacked some functionality I wanted which I found was provided by the CAS version of the same model line. Thus my purchase of the TI Nspire CAS calculator.

    Important note to users of other/past graphing calculators: the Nspire line from TI is very focused on teaching math at high school and college levels. It's document based UI is more like a computer program than the old million button scientific graphing calculators before it.

    The keyboard is three part:
    top: navigation, both on screen (touch pad) and primary menus/features
    mid: numeric and basic operators along with some more menus and shortcut keys
    bot: alphabetic keyboard (not QWERTY!) for entry of function names and such along with some special function keys

    Pros:
    1. Fast - the calculations and graphing are significantly faster than on my TI-89 Platinum.
    2. Extensive built in library.
    3. Document based UI - once you get used to it, you'll probably like it a lot.
    4. Scratchpad feature - easily use as calculator or for graphing without interrupting current document.
    5. Nice screen size and resolution.
    6. Programmability.
    7. Very solid feeling, well built.

    This is much better than the TI-nspire CAS because it is much easier to enter numbers and variables. I always made mistakes on the old nspire and I'm really glad I got this one. When using graphs it allows you to use a pointer like you would on a computer using a touchpad.

    Pros: design, data entry
    Cons: bulky

    I'm a rabid calculator fan and must say that the TI Nspire touchpad is by far the best calculator I've owned. Specifically, I bought the teacher bundle that includes a single license of the software. The only downside is that the manuals that came with the calculator are useless.

    The best manual for how to use the calculator I've found is: TI-Nspire Technology Cliff Notes By Steve Ouellette (2nd Edition). With this Cliff Note and the examples already installed on the calculator, you can't go wrong!

    Before I get to the warnings let me say that I love Ti calculators. I have never found one I did not like. This is an excellent calculator if used for it's intended purposes.

    1) this does not provide any new functionality over the original Ti inspire cas. The old round directional pad functions just like the track pad except it is more precise. I would even go as far as saying that this is inferior to it's predecessor.

    2) this, like it's predecessor has a full alphanumeric keyboard and high level algebraic manipulation software. Therefore it is not permitted on ANY standardized test. Not the sat's not the ap exams. Many college professors will not allow these during exams.

    3) unlike the 80 and 90 series calculators there is no program editor. On top of that advanced math operations are not allowed in a function. Programs allow you to expand the functionality of your calculator. My random NxN invertable matrix generator has saved me hours of time over the course of my life and last I checked was downloaded by more than 12 million people. But programs like that cannot be written on or be run on any of the inspire line of calculators. This is why there is very little information on the web about how to use it better, you can't.

    4) there are numerous small over sites that were not present in the 80 or 90 lines, such as lack of direct access to stored variables and no customization of menues, that advanced users will find irksome.

    So here is what I reccomend:
    Do not buy this calculator unless you are a collector.

    If you are a colege student who needs to take a few advanced math courses. Get the old inspire cas

    If you are a math major get an 89 or 92+ and really learn to use them well. go to ticalc.
