From an engineering student's standpoint, the ti-89 remains the far superior calculator, due to having a much better computer algebra system (TI itself says so).

I look forward to a rebuilt ti-89 around a more modern processor such as an ARM9 (thats what the inspire is based on from what I recall). I mean the 68k in there now is usually fine, but my 89 grinds to a halt when manipulating matrices with complex numbers and in vector calculus (why doesn't AMS have built in fuctions for gradient, curl, divergence and laplacian?).

I vote for voyager 200+, and since my 89 is now completely shot, I may get one. (they have an internal clock! and color screen!)

I'm either getting a TI-Nspire with CAS or a TI-89 (titanium or regular) when I go to college, seeing as how my current TI-84+ is lent from the school.

I am holding out to see what the developments are. I am not in a rush; I don't graduate until next year, and until then, my 84 will serve just fine. XD

Yeah, my 89 is on loan, so I'm thinking of buying an Nspire CAS and then running an 89 emulator.

I was in a focus group for the TI-Nspire. Stick with your TI-89s, everybody. If you don't have one, purchase a TI-89, then stick with it.

I think everyone in the group I was in (it was at a math competition) was annoyed when one of the people in the group noticed you couldn't program with the TI-Nspire keypad, and the presenter replied "well, you're not our target audience."

Bah! Give me simple scientific calculator which supports everything up to hyperbolic functions and complex numbers, Karl Rottmann's Mathematische Formelsammlung and a decent supply of paper, and I don't need your fancy TI-Nspire.

Ok, slightly more seriously: Is the handheld TI-Nspire not programmable? In that case, I'd much rather stick with my TI-83 Plus, or buy a TI-89. Except, of course, the only calculator I'm allowed to bring to exams is HP-30S, and that I less and less frequently do mathematics where calculators are an asset.

I'm pretty sure, at least in the original, the TI-Nspire only had programming functions with the TI-84 keypad, and I'm not sure about the CAS, though Wikipedia says it also has limited programming capabilities. Either way, I suspect the programming won't be anywhere near as accessible on the TI-Nspire as it was on the 80 series.

Supposedly, they're releasing an OS release to help this, but either way, I think you're better off buying an 89, especially if you're seriously into math- the TI-Nspire seems geared more towards high school students, and I think the CAS still won't be as good as an 89. It's subjective, though, so choose what you want.

I have an 89, but use my 83 more often. Not that that's saying much, because physics at my level doesn't involve many numbers :-\

Well... nothing, really. I'm sure every decent university-level formulae book is equivalent. It's just that Rottmann has been a faithful companion of NUST (Norwegian University of Science and Technology) and NIT (It's predecessor, Norwegian Institute of Technology) students for many years.

Okay, the equivalent book at my university (and I guess in most Swedish unis) would be http://www.amazon.com/Mathematics-Handb ... 3540655697 . Never really had much use of it though. The tables of integrals and transforms have helped save time during some physics exams.

My maths C teacher was sent one of these to test, and he told me to use it for the term to assess it as to its usefulness for our course. I can imagine one being useful, just for checking certain things...but definitely not for every student. 84s reign supreme in our school.

(I was reviewing it for what we use it for though..keep that in mind)

The 89 was nice, especially when I was doing stuff with matrices. As for less powered calculators, I very much preferred the 86 to the 83. Things like the Voyager brick just looked more obnoxious and unnecessary than anything else.

You can get colors with a TI 83 as well! There are methods to overload the screen pixels, which give you blue lines :P
There's a chance they won't go away after that though :P

You can also simulate greyscale by flipping pixels on and off fast enough :)

High school was fun :P

You know, I was actually looking at these the other day, specifically in comparison to the 89 titanium - I'll be getting a calculator, probably for christmas, and I currently have the 83 plus. I don't really get what this CAS is, but the Nspire CAS supposedly won't be out for another year - I'd rather just get the 89 Titanium, though, yes, the Nspire does look nice, limited programming abilities - I've had my 83 since 8th grade (this is my 4th year) and I've become quite used to my programs - saves a huge amount of time on tests.

The 89 Titanium is supposed to have a superior CAS to the nspire CAS, anyway. From playing with my teacher's npsire this weekend, I love my 89 more than this, as the simple interface is exactly what I love about TI.

None of my classes will allow me to use a programmable calculator anymore. Heck in all of my calculus/diffeq courses I was never allowed to use a calculator period!

So really, this would serve no purpose except to look pretty and use at home. Still...it does look pretty cool....

If it can do a fast fourier transform I'll get it :P

I have a ti89 titanium. It was mismarked at the store, I'd guess ($100.90 instead of probably $190)--I was fucking psyched. It's fine for me, I probably won't be getting another calculator anytime soon. Pirated Maple 11 is good enough for me! ;-P

[edit:] But I would like to read some sort of independent review of the calculator, preferably by someone who knew their stuff, whose writing was geared towards people who knew their stuff, and didn't work for ti.

[edit again:] Fixed the second there to a their. On any other forum I would have left it, but here I just can't somehow.

I found one in amazon, but it has been offering it for a while.

Also, my friend Leo had a TI-Nspire with CAS on Friday. He doesn't recommend it, though. XD

Some eBay stores are selling them, apparently.

I'll get one for Newtonmas, I think. I like the TI-89 I have on loan, but I would like more speed and don't mind decreased programming capabilities too much (they say they may add more programming capability in firmware updates).

And they're so pretty.

The point isn't that these calculators are useful for engineers or math students - they look like they would be absolutely phenomenal for teaching calculus, precalc, and trig. That's what they are designed for. They may not be the most useful for solving real-world problems, but as teaching tools they may be unbeatable. I'm sure my high school math teachers are excited - they were really into getting a graphing calculator in the hands of all of their students to show graphs and so forth, and this type of thing would take that to the next level.

As someone teaching calculus, I would love for my students to be able to look at a formula for a function and figure out at least the general features of the graph without having to plot a whole bunch of points first, but this is a skill that very few of them possess. If calculators like this would help, I'm all for them.

Unfortunately, your poll doesn't include an option for me. I haven't used a graphing calculator to do anything I couldn't do with a scientific calculator in years, and a new line of calculators won't change that. On the other hand, I'm very excited about the possibilities these calculators open up as teaching tools.

The price is a little scary though - 190$ per at amazon, or 1550$ for a teacher's kit with 10 calculators.

I have my TI-Nspire CAS+ now.

The display and GUI are excellent, pointing is good. Straightforward filesystem, windowing is tolerable. Much quicker than TI-89 Titanium for most things.

The Graphing and Geometry app has interesting controls; very tactile.

I got mine today. The interface is nice and snappy, the large screen is very nice. The buttons take a little getting used to, but they're tolerable.

But TI really dropped the ball when it comes to programming. Even with the improvements of the latest OS, the programming capabilities of this thing are, well, nonexistant. If you want to do nothing but perform mathematical calculations, it's all right. For anything else it's useless.
