What do you get for the mathematician hobbyist who has everything except a Mathematica license? How about a Mathematica license?
Wolfram research has started selling a "Home Edition" of Mathematica for $295, which ain't pocket change, but it's a darn sight cheaper than the commercial retail price of $2495 (which is what we professional's pay). The thing is, the Home Edition is EXACTLY the same as the commercial version (with the exception of 64-bit functionality), not some watered down Mathematica-Lite. (I'm looking at Mathematica Player.)
Since I happen to know there is a strong correlation among my readers of math-geeks and music-geeks, here is something to make both hemispheres happy.
