Well, they can stop the casual copying all right. And along with it they'll lose all the customers they would have had, if those "casual" copiers had played with the software long enough to know they wanted it. 30 day evaluation copies are nonsense. People don't have time enough to see if they'll REALLY use it in that time. What they're trying to protect is their sales of software to impulse, uninformed, misdirected, mislead consumers. If someone KNOWS they'll use the software (and hasn't discovered a few weeks or months later that they'd made a mistake and don't need it) they'll buy it. They'll buy it again and again. They're not really interested in SATISFIED customers (and this isn't directed at CL here...it's the industry in general and please don't tell me about perfect worlds or people better than I am)... I wish I could get a 50% refund on every piece of software I've purchased that performed at 50% of the level it was advertised to perform at. End of rant
