Oh, come on! Considering the approximately $2,000 price for standard commercial versions of Mathematica, MatLab, and Maple, the $295 for the home version of Mathematica is quite reasonable. If you want to freeload, get Sage (which is quite good, btw).
Wolfram now has a version of Mathematica called "Starter" which costs $995 CAD and can be used for commercial purposes (unlike the home version). The Starter version only gets upgrades for one year, but you can keep using it after one year.
