Not sure what you mean by shapes ?

Like hand-drawn lines/fills ?
If that's what you're talking about, then yes, it's way faster and lighter in memory than using sprites. (TI's lua image is very bad....).
But some games do use images and are still efficient.

I don't know much about non-TI-calcs. The TI-89 really is the best for school, but it is not allowed on the ACT. You need a TI-84+ for that (best calc allowed on the ACT)

Wrong, the Non-cas CX is the best calc for the ACT.

I recommend a CX Cas.

Then you miss out on the larger library of original games and audience. :P

Personally I don't mind the CX for math, but its interface is harder to get used to than a regular calc and it's totally locked down (for example, if Ndless 3.2 ever comes out, TI will immediately release a new OS that blocks it).

And yeah the CX Cas is banned from the ACT and some other american tests.

By now, for developing Ndless on a new OS version, it probably makes more sense to wait for the next OS version.
Granted, we've been awaiting for TI to fix up their bugs for more than a year... but past patterns tell us that they're likely to release a new OS version some time before, or during, the next school year.
By providing a relatively easy way to switch between OS 3.1 and 3.2, the TI-Planet fork of nLaunch, and later the fork of nLaunch CX, have reduced the incentive for making versions of Ndless tailored to the OS 3.2.x versions. nLaunch provides groundwork for making Ndless on any OS version without having to find new vulnerabilities in the OS... as long as a given calculator keeps a vulnerable boot2 versions. In the mid-term and long-term, a majority of calculators will get upgraded, and few users will use the RS232 port to downgrade the boot2... but then, the majority of users which cannot access the power and goodies (assuming no other exploit is found in the meantime) provided native code by will strongly hate TI, and their resent will help fuel new powerful attacks against TI's business model.

Indeed, I think it would make very little sense to focus so much energy for a release for OS 3.2 only to see it blocked the day after. Of course, if they ever figure out how to permanently block downgrading below OS 3.2 in newer OSes, then a 3.2 release might be in order.

Maybe they'll stop or slack down if the Prime is ever successfull. I know over here the 83+/84+/89T are very successful in school, but that Staples has pulled the Nspire CX from their stores.

The Prime isn't less locked down, AFAWCT :(

And it seems that TI has started shipping a new "3.2.4.1237" version, with (seemingly, although we've seen a single report so far, and we haven't been able to get our hands on the OS yet) a highly unwelcome gift: http://tiplanet.org/forum/viewtopic.php?f=17&t=12304
I'm not making front page news until we can confirm this.
[EDIT: it's confirmed: anti-downgrade protection enforced by a new boot2 version, which is probably not vulnerable to the nLaunch exploit.]

There is one positive thing about the Prime, though: At least it has a decent BASIC language built-in, and appears to have an on-calc editor. If the OS isn't as buggy as the 39gII and that the language uses the same interpreter, then ASM will not even be needed for most 2D games. The problems will come for people who want to go further, such as porting DOOM.

I personally just stick to my TI-84+, TI-84+CSE and Casio PRIZM for development from now on (although I am really only developing for the CSE now), and even for general use I prefer these 3 calcs. Of course for school the Nspire is a great tool, but don't count on it to run your favorite games, since it might be locked from the start.

Sorry to post a year later but, in the end, I didn't buy the calculator. I didn't have enough money to get it and, besides, the topics I was studying didn't require a graphing calculator. But, now, I've started a more complex course.

So, since the HP Prime has officially arrived and some changes have happened, is everyone's view on the Nspire vs Prime the same? Especially, since I'm in the UK, so teacher support is not a major factor here unlike in the US...

If you plan to buy the calculator both for class and hobbyism programming, then you should probably get the HP Prime, else the TI-Nspire might be better. Of course it also depends if you like touchscreens better than touchpads, though. The HP Prime is also faster, but less stable (for now).
