True, but don't forget that Apple are practically guaranteed to have made money from you already when they sold you the machine that runs the OS. Microsoft don't have that advantage; they get nothing at all if you pirate the software. I'll openly admit that when I was a student I did run a pirate copy of windows on one of my two PCs, simply due to the fact that money was tight. However, as soon as I had a proper job, I "upgraded" to a legitimate copy, simply because my conscience didn't like the fact that the software was stolen and nagged me to sort it out as soon as I could afford to. Besides, despite various niggles, I reckon that XP home is probably worth the £57 I paid for my genuine copy.
