Several computer algebra systems are available to Linux users. I even have looked at a few of them in this column, but for this issue, I discuss OpenAxiom. OpenAxiom actually is a fork of Axiom. Axiom originally was developed at IBM under the name ScratchPad. Development started in 1971, so Axiom is as old as I am, and almost as smart.
Either the Samsung Galaxy Axiom or the LG Phoenix?
The Phoenix has a known root solution and a perfect Cyanogenmod.
The Axiom has much better hardware and you have to use Poot. No Cyanogenmod is available for the Axiom (as far as my research shows).
Which should I get? They are both relatively cheap.
