Freemat and Sage 6

Freemat is a free matlab clone. For past six months I have been using MacBook Pro and its not so easy to run Linux on this machine along with Mac's legacy operating system and that is where Freemat comes in. For most of my normal work its an awesome replacement to both matlab and octave.
Sagemath has recently come up with the new version of their software which I think has been due for now a long time. To install on Mac was quite easy and it got integrated with my google chrome. Before that I never really seriously experimented with sage because I always could find Maple but now I think Sage will be my default choice for all my work and its pretty neat.
