Is HP Prime going out of production?

[parisse]

Anders, I think you are a little confused : KhiCAS is the TI port of Giac/Xcas tha I made some time ago, it is a ndless application, not the built-in TI CAS (you can run it perfectly legally on a non-CAS nspire). All commands of Giac are enabled on KhiCAS, therefore you have more commands than on the Prime (where some commands are disabled), and you also have support for multi-precision floats and interval arithmetic (GMP+MPFR+MPFI). But there is only poor integration with the TI system (you can only work inside your khicas document) and there is no support, I mean if there is a bug (e.g. a bug that requires rebooting the calc), I can never warrant I will be able to fix it (and it takes much more time to fix a bug on this platform because I do not have efficient debugging tools). It should be considered as a geek application or a useful addition on non-CAS nspire.
