Upgrading CAS calculator

[kensan]

At the moment I am using this CAS


Is there any point upgrading for year 12 next year to the new CAS CX with colour screen?

I'm just wondering if anyone has used both and if it would be a benefit for next year.
Thanks

Nah you're not missing out on anything, they both run the same operating systems. I think there are a few minor improvements, but I don't think they justify shelling out for.

I have that grey TI-Nspire CAS you pictured there. I haven't used the CX, but I have used the black ti-nspire. The keyboard layout for the CX seems quite similar to the black nspire. If you look at the grey ti-nspire, you have dedicated buttons for greater than, less than, sin, cos etc. On the black nspire you don't. Looking at pictures/videos of the CX, that seems to operate the same way.

There aren't dedicated buttons for those functions. You press ctrl and some button, and it comes up with a menu on the screen. For the inequality type stuff, you press CTRL + = and you get that digital menu. From there you have to select and press ">" etc. from that menu. Same thing for the trig functions and for pi, i etc.

It's probably that I'm not used to it, but I find it A LOT faster and simpler to just press one button, rather than having to use a menu every time. There's quite a few other small user interface annoyances I found with the black TI-nspire, and from what I've seen on the net about that CX, there's annoyances have carried over. I assume TI thought they had made design "improvements" and stuck with that misconception.

So yeah, I'm sticking with the one I already have.

Wow thanks so much for that detailed response 
I've tried the black one too, only to use the touch pad though
My brother is getting the CX for year 9 next year, so I'll give it a shot then, but for the time being I'll stick with the one I'm using at the moment as I don't have any problems with it. Thanks again
