Yeah, sounds more "removing stuff to make a budget calc" than "removing stuff to piss off the community". Hope they set the price accordingly so people would buy a CM if they don't need all the features of the CX.
So, priced as if it were made out of solid Gold instead of solid Platinum?

First of all, you're almost certainly going to have to at least be familiar with ASM to write a good CAS. Sorry, it just works out that way.
Secondly, I would highly recommend a numerical core to any math product. The symbolic manipulations available in a CAS are useful. However, they're far more powerful when combined with a numerical package. The majority of those functions you see on the Wolfram site (~99% of which are never used) are numerical algorithms, not symbolic functions. To get a basic CAS/numerical math package up, you pretty much need the following capabilities:
Symbolic differentiation
Symbolic integration (which is a formally undecidable problem, so don't worry about restricting the range of functions allowed as input)
Symbolic simplification
Array generation (generate arrays of numbers according to some rule)
Map (maps a function accepting 1 argument to each element of an array)
Symbolic functions
Eval (Numerically evaluates a user defined symbolic function at a point)
Plot <function>
Sin/Cos/Tan/ArcSin/ArcCos/ArcTan/CoSecant/Secant/Cotangent
Prime(n) (returns the nth prime number)
Numerical differentiation
Numerical integeration
Elementary operations (+,-,*,/,^,Logn,Abs, etc... These are generally expected to work on all numerical data types without complaint)
Some method of writing programs (either with a built-in scripting language or with a Well-documented API. Yes, this is entirely necessary.)
Rand (generates a random decimal number)
RandInt (generates a random integer)
Keep in mind that this is about the minimum to have a useful CAS.

If you're going to do graphics stuff, I'd recommend either staying away from pixels as the unit of measurement or allowing programs to get the screen size to do their own scaling.

That's why I said it's "currently impossible." To the best of my knowledge, no one knows how to do it.

Boot1 is held in ROM, which is currently impossible to modify.
Also, the Nspire could indeed decrypt the OS if it wanted to (thank god it doesn't). It's enabled by something called Public-key cryptography, which basically allows anyone to verify/decrypt the data, but only those possessing the secret keys to sign the data so that it can be verified.

The private keys are not located anywhere in the OS. That's why they're called private keys.

Please calm down.
Also, finding games is up to you. We highly recommend using Google for game reviews.

I've gotten a lot of work done with the libraries and the beginnings of Khavi Scripting language. This project is just absolutely massive...

I just lost The Game.
Thanks Geekboy >.>

Eiyeron, please don't troll. The Prizm, while not as fast as some of the other Casio calculators, is still faster than all of the 83 and 84+ series calculators from TI. Furthermore, the Prizm is more than fast enough to run some impressive projects, especially since it can be overclocked.

Haven't even started the Prizm one Powder comes after my other major projects, so I'm waiting before I attempt it.
