Books about CAS

[jonmoore]

I'm not particularly a fan of either Derive or XCas (I'm a hardcore Mathematica user of many years) but having worked with XCas on the 50g and Prime (and 48GX before that), I believe XCas is a better pocket calculator CAS solution.

In recent years I've dabbled in Derive as it's built into a great HP-41cx emulator on iOS - i41cx. It's a klutzy integration so that might have coloured my view, but I think Bernard Parisse deserves a lot of praise with regards to just how far he's pushed CAS on pocket calculators.

I believe that the Casio Classpad now uses XCas too. But much like GeoGebra, they've changed many of the operator naming conventions, however the underlying UX has a very XCas feel to it.

My favourite XCas mobile implementation is PocketCAS on iOS, it does a better job of being a 'pocket' Mathematica, than iOS Mathematica itself.
