Thanks for the Nspire info.
My concern about that calculator is that it's a not too modern model, I like the Casio because I like the brand and it's a new product, so (maybe just in my head) it means modern components, longer life, optimized and improved performance.

Welcome aboard!

The TI Nspire CX will have had some hardware revisions over the years since its release (my CX CAS is a revision T from January 2015), but no real change in specs.

The fx-CG50 may be "brand new", but it's very similar to the earlier CG10/CG20 model, but with a faster CPU. (There are some changes to the address layout, which broke a lot of third party applications that assumed the frame buffer was at a particular address, etc.)

Quote:So, as you have the Numworks and the Nspire, which model do you recommend?

You addressed that to Tom and I don't know which he'd recommend. I don't have a Numworks, but I've played with one and used the emulator (and even contributed some patches on Github). The colour scheme on the keyboard is its worst feature - very hard on my aging eyes - I even raised that as an issue on Github! Also, the software is still a bit immature. The answers it spits out are nowhere near as good as they could be. But it's still being improved. They have their own programming team, plus free help from the community! (Insert dig at SwissMicros here.) So between the Numworks and the TI Nspire CX, I'd currently go for the Nspire unless price and physical size are also important, in which case the Numworks gains a few more points.

Quote:Also, do you have the CG50? If you do, how does it feel? I have the new Casio Classwiz and the buttons feel a bit flimsy (it's normal as it is a £20 calculator!)

I have the fx-991EX Classwiz and the fx-CG50, The buttons on the CG50 are basically scaled up versions of the ones on the Classwiz. They need slightly more force to actuate because they are bigger, and have about the same level of clickiness, i.e. none at all!

Quote:Too many questions, I know!
Thanks!

Have you considered the HP Prime? It's quite reasonably priced on Amazon UK at the moment. You can't program it in Python though. It's built in HP Prime Programming Language (HP PPL for short) isn't object-oriented at all. It's loosely similar to Pascal or Modula-2 but not strongly typed and missing things like structured data types beyond the built-in types such as matrices/vectors and lists. I'm planning to buy one soon anyway!
