Need help deciding on a calculator

[kikko]

I had no idea where to post this.

Anyways, I want to buy a graphing calculator. I am deciding between a Ti-89 Titanium and a Ti-Nspire CX. Or, is there another calculator you suggest?

Right now I have a Ti-30XS, and I like the kind of logic used to enter my math into that. I don't like the reverse logic or whatever the other type is, that I believe CaSiO uses. Any help?

I'd have suggested an app for your touchscreen device these days. example
Running a script language on a tablet or a netbook? - I've always found graphing calculators to be limited.

You didn't notice that we have a Calculators forum.
