You could also try OSX, but that would require buying a new computer... I switched from Windows to Mac about 3 years ago, and I've never had any problems really. Nothing more than you can't get some software or run a few minor programs on OSX. OSX is really user friendly, and it doesn't take much adjustment to go from Windows to Mac. And OSX is built on Linux, so it's solid as hell. Just another suggestion.
Math is more than formulas or equations; it's logic, it's rationality, it's using your mind to solve the biggest mysteries we know.
