Bought 2nd Nspire CAS / what's SAGE

I just bought a Nspire CAS Touchscreen for $50, the best calculator available.  With the 3.2 firmware update, Nspire CAS has more features and math algorithms than TI-89 Titanium.  I previous bought a Nspire CAS in 2009.

Maxima is free CAS for Windows which has all the features of SAGE in universities, yet is a lot smaller filesize.  It is based on DOE-MACSYMA. Its abilities include symbolic integration, 3D plotting, and an ODE solver.

I found a free CAS running on Ubuntu (1.5 GB) in a Virtual Box image.  This "Sage" software might exceed Nspire CAS functionality and its free.  I know Sage is used by universities who can't afford commercial CAS applications.
