The TI-Nspire used to be 10x worse than it used to be, though.
Why do I feel like I've entered a temporal loop? (Hey, look, I think I just saw yesterday's today version of myself...)

A final note, the North American Prizm (fx-CG10) seems to be a bit crippled than the other Prizm (fx-CG20). From what it sounds like, images and movies (in CASIO's g3p format) created on a fx-CG20 cannot be opened on a fx-CG10, unless it was provided by Casio (On Casio's site you can download images/movies from their gallery: http://edu.casio.com/products/cg_series/materials.html) The fx-CG20 can open images and movies from both the fx-CG20 and fx-CG10. This was probably done so it would conform to testing standards in the US.
Exactly. The images and flipbook-like image collections are of proprietary file types. This pleases testing agencies and school administrations.

I personally believe that it will have some sort of BASIC language for it, considering that the lower right hand button has "EXE" on it, if not at least assembler support.
*tloz pictures Project M in color*
EXE is Casio's standard key for execution of commands - similar to "Enter" or "=" on other calculators. It has nothing specifically to do with programming per se.

61Kb of RAM really? It is going to need 162Kb if video RAM just to display a full screen picture.
Well, apparently not, because it has 30+ pre-loaded images and flipbook-like image-sequences. Part of the beauty of a high-res screen is the ability to superimpose mathematics directly on top of image files.

Nah TI is not discontinuing the whole line. If you read in the latest pages of the 84+ topic, you'll see that it is only in Germany and Swiss, as well as a few other european countries. However, if TI decides to change their mind and discontinue it everywhere in a near future, they're pretty much screwed.
It's only a matter of time. That's the beginning of the end for the 84. Same process happened with the 85 and 86, despite major protestations and signed petitions by teachers.

I'm guessing you accidentally put your new post in the quotes. Nice to meet you! (to Tresio)
Yeah - noticed that a few seconds after I posted. Sorry - it's fixed now. And thanks for the greeting - I was searching the web for Prizm info, and found your forums! (Wish these had existed when I was in high school programming the TI-81...)

edit: "With Casio, academic achievement never looked so good. The new fx-CG10/PRIZM is approved for use on the ACT, PSAT, SAT and AP Exams."
if it's approved on all those exams, i doubt the math functions are as helpful as a nSpire CAS or TI 89, though.
The Prizm is definitely a non-CAS calculator. Ignoring programming for a moment, and considering only the out-of-the-box calculation capabilities, it's very difficult to compare Prizm and TI-89, because they have very different intended purposes. Similarly with NSpire CAS (though NSpire non-CAS would allow a more fair comparison).

In the specs, it says it gets about 140 hours on batteries, I believe.
Wow 140 hours, I wonder if that's at the full processing power, cuz if it's the case, it's really epic o.o.
140 hours of battery life is estimated based on 5 minutes of processor-heavy calculations and 55 minutes of "rest" per hour. (This is the graphing calculator standard for estimated battery use.) For reference, most current GCs offer 120-140 hours of life. Helpful in this regard is the battery usage meter in Prizm's status bar. The Prizm will also accept an optional 85-hour rechargeable battery.
