* has CAS
* 320x240 pixel resolution with multiple shades of gray (that is really high resolution!)
* processor is 6 times faster than TI-89 Titanium
* 16MB of computing memory and 20MB of storage memory (Yeah, that's right MegaBytes, not KiloBytes!)
* Available in Q2 2007

I believe the only hope that CASIO has against this type of competition, is that hopefully the TI-Nspire CAS is really expensive which may turn down some buyers or CASIO's fx-9860SD can compete against the TI-Nspire CAS. If the release of the fx-9860 SDK comes before TI-Nspire, that may hopefully attract a bit more people to the fx-9860.

-CAS: normal, not really upgrade from ti-89 titanium.
-Keyboard: the letters keys are small and seems to be difficult to operate.
-Bugs: still many.
-Spreed sheet:uhm, i think its SS is good!
-Geometry graph: not really improved.
-GRAY SCALE: A GREAT THING THAT CASIO...!
-Operate history: long.
-Its SDK: not soon release.
-Page layout: just as our e-act.

How can titanium survive ?How much will the TI-Nspire CAS+ math and science learning handheld or TI-Nspire CAS computer software cost?
Dealers are likely to price the TI-Nspire CAS+ handheld (or single-user computer software) similar to the TI-89 Titanium. Please contact dealers for exact pricing information.
Will the TI-89 Titanium be phased out?
Texas Instruments does not have any plans at this time to phase out TI-89 Titanium.

Competition is high. Good for us, Casio has to react.

And the ClassPad's touchscreen keyboard is easy?-Keyboard: the letters keys are small and seems to be difficult to operate.
Well, at this time, that is meaningless. The product is not released yet, and won't be for some months. As long as the ClassPad has been out, it still has significant bugs.-Bugs: still many.
Again, it's not a final product yet. However, just the ability to see several views of the same problem could be very helpful, especially for the student.-CAS: normal, not really upgrade from ti-89 titanium.
-Geometry graph: not really improved.
In general, I'm looking forward to the release of the Ti-Nspire. It is a very interesting device, with several real improvements over present graphing calculators of all brands.
By the way... I really don't feel the Ti-Nspire is competition for the AFX / CFX / FX. I think it is more of a threat to the ClassPad. Perhaps, I hope, it will prompt Casio to really improve the ClassPad and bring it significantly closer to what it really should have been in the first place.

Well what about the fx-9860? The SuperH processor in the fx-9860 uses superscalar processing providing fast execution speeds. So, the fx-9860 might be actually faster than the TI-Nspire CAS. Also, the fx-9860SD can retain more memory for storage through an SD card than a TI-Nspire CAS.
That reminds me, does anyone have an fx-9860SD they are willing to bargain with me? If I could get one, then maybe I could use my fx-9860g for hardware experimentation and find out more on the fx-9860.

I think, for normal operation (not for putting Wikipedia on eActivities), it works well. In O.S 2.2 /3.0 the touchpad controller was improved a lot. Sincerely, see the Nspire's "sparse" keyboard, you'll take seconds to guess where is the key, because the keys are spread, small, and the keyboard is so dense.
And navigating such extensive menus only with a keypad is annoying, i'll prefer a stylus for direct operation.
On input/interface i give 3/10 to this calc. For sure, the big deal of the Nspire is the larger RAM and the better processor (could have? ). to knock out calculations. is the first release of a calc with RAM in "mb's" ..

hm ... the FX9860 can use 2GB in SD cards. So it might be the first with flash in "GB's"
Not the first, no. HPs can use SD cards, and have been able to for some time.

True, but CASIO invented the graphing calculator.
Anyways, has anyone considered bargaining a fx-9860SD with me?

1. TI-NSpire CAS+ (With CAS)
2. TI-NSpire (Without CAS)
3. TI-NSpire CAS+ for the PC - The CAS software that runs on the PC.

With this they reach (for example) two sectors of the Portuguese market. One is the high school where CAS can't be used in exams and the other is the university where CAS is needed. As these two versions only have a little difference imagine high school students incorporating CAS as a good helper in the exam.1. TI-NSpire CAS+ (With CAS)
2. TI-NSpire (Without CAS)
Even if this would be possible unless the version without CAS has a similar price to fx-9860 the most part of the buyers won't choose it. Mainly because they don't know what is CAS and don't bother about that.

Hmm. As I understand it, the TI NSpire is not a calculator but a math learning machine. The one with a CAS isn't really programmable (apparently you can enter functions, but there is no programming language and no program editor), and it certainly doesn't seem to be intended as a means of solving particular problem in that a calculator is intended to function.

There's also the non-CAS version, which supports a snap-in keyboard that fully emulates the TI 84 Plus. It's not of interest to me, but others might consider this handheld to cover their programming needs.
As for being expensive, they don't seem to be, really. The CAS version can be had for US$137, and the non-CAS for US$134. That seems pretty reasonable for what the calculators do.
Perhaps these machines will inspire and encourage Casio to come up with something that can compete with them, should they sell well. We'll have to see. I'm sure the initial batches will struggle with bugs and such, much as any complex calculator. (Remember the first few versions of the ClassPad's software, which continues to evolve today, as far as I can tell- Not to mention the display issues.) But I, myself, will be keeping an eye on this machine. Perhaps Casio will do the same.

Since the TI-Nspire is such a new product, some of the features of previous calculators were left off, such as programming. As more development is done, Texas Instruments will continue to update the operating system and add more advanced programming to the TI-Nspire.
#26

Someone emailed TI about the programming capabilities of the TI-Nspire:
No programming capabilities...
BASIC programming is supported, however, just like on the TI-89. Not sure if all statements are there. But, for computational / mathematical purposes, programming is available.

I plan to purchase the CAS version of the TI-Nspire (not the one with the snap-in TI 84 keyboard). I realize that this is a Casio forum, but there is also interest here in new developments in the calculator world, no matter what the brand, so I'll ask this-
Is anyone interested in my impressions of this machine? If so, I'll post here, but if not, I'll just stick to the TI forums.
I'm interested to compare notes, but if you don't have it yet, what impressions? Based on specs alone?
Here are some of my early impressions (only had it for about a week). Rather than paying for OS v3, for the same money, I ended up having a new (and, sorry to say, possibly more exciting) calc.
The (off-beat looking) keyboard is actually very easy to use and (contrary to my pre-sale concerns) I have yet to press the wrong key (and without trying to be extra careful). The CAS is basically the same as that of the TI-89 Titanium, but there are also minor (?) differences. Many CTRL shortcuts are available (all the common ones are there, CTRL-S [Save], CTRL-C [Copy], CTRL-V [Paste], etc.)
A major difference from the TI89/T: No 3-D graphs.
Battery life is as good as that of the TI-89/T, because I read some false comment about the battery dying in only a few (about 3.5 was quoted) hours. Not so. Many hours/day of operation for about a week now, and the battery indication still says 100% full.
Firmware upgrade is fully automatic (directly from the Internet) using the Link software and a standard USB cable.
There are as many similarities with the TI-89/T as there are differences. The 'document' concept (different from Classpad's eActivity, yet similar in principle) is very helpful, in that you keep complete multi-page calculator sessions, separate.
eActivities are in a separate environment, while 'documents' are always there, everything you do is part of a document. No limit to how many pages you can have in a document, AFAIK.
Programming is inline (no separate program editor). Just define the program or function on the regular calculator entry screen, and the definition even takes a place in the history screen, just like all calculations. So, you can easily call it back, change it, and re-submit it (ENTER) to change the function or program.
Screen is great (like the TI-89's but higher resolution). 3 font sizes with mild differences among them.
Speed is great.
Graph is like the TI-89/T's, only with a better UI.
Geometry works along with Graph (on the same screen) and takes a little getting used to (you probably need to read the manual about how to use the pointer and grab stuff, it won't come naturally how to perform some of the actions). But, once you understand the philosophy is quite simple.
Possibly the most intuitive List/Statistics screen I've seen.
The manual needs some work. A lot of topics are not covered well, or at all (e.g., function is covered, program isn't, but it turns out to be same).
Variable recall is very simple (a single button will bring a pop-up list with all defined variables, functions, etc. sorted alphabetically to pick from). Too bad they didn't think to delete a variable right there by pressing DEL.
Another nice difference from the TI-89/T (and I believe Classpad, too) is that both opening and closing parentheses are automatically matched. So, you can 2+3)/2 ENTER, or sin(3 ENTER. It even shows the assumed parentheses in lighter greyed font.
I'll write more specific details if there is interest. Especially, as to how it compares to the Classpad if you need to keep it on-topic.

Actually, it is well suited to students' needs as well. One can link different representations of the same problem together, allowing several different ways of visualizing the problem, for instance. I don't know all the details of this yet. I'm just reading the manuals and watching flash demonstrations if the calculator.
As for the price, the CAS version can be had for about US$ 135.00 here. The Classpad 330 goes for about US$ 145.00.

The lack of a seriuos programming language (As our Lua implementation) is certainly a flaw, but is matter of time and a developer to get an equivalent on the TI
#32

Sounds nice, seems to be that TI implemented a CAS somewhat similar to Mathcad, you do an entire document and not half calculations (although we can do it as an eactivity)
For engineers i see it way powerful, for students... i have a doubts. How much does it cost??
The main difference from an eActivity (as I see it) is that an eActivity is basically a list of links to various applications. You need to click on the link to open up the related window but while in the list you only see the shortcut to the application, not the screen itself.
The 'document' or 'problem', on the other hand, is a list of the actual (miniaturized) windows (or 'pages') of the various applications, at their current state. And, one also has the ability to combine up to 4 (same or different) applications in a single window (page), like having a smaller eActivity within an eActivity. All definitions in any of the pages are accessible by any application in a different page. But different 'documents' or 'problems' are isolated from each other. Very powerful!
(But, I still would like to have a way to define global variables, functions, etc. so they do not have to be replicated in new documents. Maybe it's possible, I don't know yet. The way I currently do this is to create a document with all my global definitions which I update as needed, and start a new document by saving-as from that document. But, that replicates the content, and it is a needless waste of valuable memory, especially as the size of the "global" definitions grows.)

You could also try the 30-day PC demo (if you have Win-based machine):
http://education.ti....contentpaneid=7
But the demo seems to lack some functionality of the actual unit, for example, the ability to recall a definition (for example, a program defitinion that has been erased from the history screen).
You can even set it to display exactly as it would on the actual device, to check out the true resolution instead of your PC's.

I got it a couple of days ago. I'm impressed with this calculator. Contrary to what is said about the TI Nspire, the battery life is pretty good. It normally runs on 4AAA batteries, but I was surprised that the TI Nspire can still run with only two batteries!
Keyboard is a bit better than the TI-89 in my opinion. Don't need to press SHIFT, ALPHA to type in letters. The green letters keys are extruded a bit higher than the non-letter keys so you can actually feel which key you are pressing.
The LCD screen is sooo awesome and this calculator probably has the best user interface.
However, I've heard that most people say that the TI Nspire isn't geared towards engineering. I'll have to agree with them also. The CAS is okay, but the true power of the TI Nspire CAS and the TI Nspire (84+ emulation) comes from it's geometric capabilities. I guess that's what the TI Nspire is designed for. It's user friendly interface and geometric capabilities would be perfect for young kids in highschool taking a course Geometry. You can grab a point on a function and manipulate it. It has tons of features that could help students with writing and understanding geometric proofs (perp. bisector, angle bisector, midpoint, polygon, circle, parallel, etc.)

Actually, buying a TI-89 or a ClassPad 300 would be a better investment if taking calculus. TI-nSpire seems more power driven toward geomtry and manipulation. Also the lack of polar graphing on the TI-nSpire is a big downer.
So you're saying that once I advance to calculus, the TI-Nspire is not my best choice of calculator? What about college math classes like Calculus 2? If I buy a calculator, it will be the one that I take with me to college, so should I forget about the Nspire and get my parents to buy me a TI-89 or a ClassPad 300? Calculators are so expensive these days that I don't want to buy another one in the next few years. What is best for these upper level math courses?
