I heard from a guy who heard from separate source weeks ago that NSpire will be three versions.

my only hope is that it will be reliable for making games as well. while calcs should be used for maths, its always good if students can entertain themselves outside classes after finishing all their works.

I'm not familiar with TI-89 lingo, but "not programs" sounds very bad...

Well... not programs is bad, but if program commands and supported in functions, then its ok (assuming strictly TIBASIC).

As for games, again if you look at the design of the calculator, it will be hard to game from a physical point of view due to to the arangement of the keys. But since the hardware is better, games will also be better prolly.

Most likely the model will be a CAS w. computer software either free or optional. Basically this is TIs attempt at a ClassPad 300+.

If the thing I heard about a non CAS version is true, why get N-spire at all. I guess you might as well stick with a z80 calc right...? (Unless you want the better games  :Ptongue.gif ) And I'm sure you can easily fake the calc as CAS or nonCAS.

As for the concept... TI is now focusing completely on CAS calcs, many of which are not permitted in school, tests, etc. Therefore, I think that it should focus on x80s and 68ks with better HW, but not so radical stuff...

Good points.

By x80s, I take it you mean TI-8x.  ;)wink.gif

Thats Exactly what Ti wants to do with this calc I believe. They don't want you to get an Nspire. They want Your School to get one. or two, ETC.

Looking in the manual, there's a introduction to the Nspire. It sounds a lot like what you would find in a marketing brochure for the calc, and from the way it's worded, It sounds like it's being marketed as a learning platform to benefit teachers learning experience. (I'd post it, but the PDF's are encrypted to disallow text copying. I don't feel like breaking the DMCA) It also talkes about a "Cradle Charging Bay" that will charge up to four 4 "connectivity sleds" (my guess: they mean Nspires, but I could be wrong. It doesn't refer to connectivity sleds anywhere else in the manual.)

If this was a calculator that student's would buy, why would the intro focus so much on how this benefits the learning experience instead of ease of use and functional power like previous calc's were marketed? Also, why would it need a charging bay for four calculators?

The more I read these docs, the more I think Handheld Powerpoint presenter, data collector for labratory work, new age interactive learning device, and less graphing calculator.

z80. But you were close enough for me to understand.

Sorry for the ambiguities. And I agree that it is no longer a real "calculator" anymore.

Also, if I remember correctly, Nspire is supposed to have a mouse controlled with arrows right? I remember some shells for the 89 used arrow based system instead of the F1, F2, etc. The arrows weren't that effective whereas the F1, F2, etc. built in was a lot faster and overall better.

Don't quote me on this, since I don't have the PDF in front of me, and really haven't read a lot on how the interface works since I focused more on the index at the back of the manual, but i believe the button in the middle of the directional star acts as some sort of trackpoint similar to how IBM does the mouse on some of their laptops. EDIT: handbook says it's a pressure sensitive directional pad for cursor movement. sounds like a trackpoint to me.

Although I'm sure it's not a graphing calculator by the way we define one, it is an interesting device nonetheless. It looks like Ti is trying to compete against PDA's in the classroom with this thing, but instead focusing on making a PDA specific for math and science learning. If it has a solid price advantage, it just might take off.

There's some images in the manual of it having test questions, reviewing notes from teachers already programmed in by the teacher, complex data capturing and analysis, as well as breakdowns of complex equations. I'm almost thinking of getting one with the CBL/CBR set just to see if it can replace the antiquated Logger Pro probe software we've been trying to kill here.

The Nspire idea sounds cool, but its just that its not a calc anymore... I just hope that any CAS updates on Nspire will also be made available for 89s, 92s, and V200.

As for pricing I think I heard that it would sell for the same as an 89T.

If it does, it won't get much sales. The people getting the 89Ti are the smart people that need it, not the people that just need a graphing calc. The people in that 89Ti price range would realize the 89 is a better deal.

Or maybe the nspire can do all that and I'm just still angry about the lack of proper programming support...

By "smart people" if you are refering to math people, then the Nspire will have a superior CAS, but in the classroom, I think teachers would rather see the 89T.

I think the Nspire lacks this: (can anyone confirm?)
1. A small loudspeaker to alert when a process is finished. (Like HP calcs)
2. A color screen. (Like Casio calc)
3. A clock to time start & stop of functions. (Like HP calcs)
4. A memory chip (SD like Casio calc and HP calc)
5. More powerful programming features. (Flags, error caching, single step, indirect memory addressing. Like HP calcs, old TI calcs.)

1) mhmm ew i dont want my calc to do noises when something is finished, imagine what would it be in a BASIC game where the calc is often in a busy state

2) that would rule but the color screen on casio is crappy, its just 3 layers or 4 i think and it look weird when the calc is tilted

3) true

4) same

5) and i hope it even have BASIC programming stuff included as well as DRAW functions at all

I can imagine taking a test and out saying "Function completed. X=32" then everyone else listening and copying it :Dbiggrin.gif

Color... give it RBG and at least 100x200 pixel screen, and I say yes.

So TI didn't like the timer idea they started with the 84+?

You can never have too much memory :)smile.gif Same for powerful functions, though I'm sure the nspire programmers will figure out some nice hacks.
