I'm all for Apple ensuring that they get their money as fraud seems to be all too easy with anonymity given by the Internet.
However, it is my understanding that the primary reasoning behind having lower educational prices is that students can finally afford software they want to use but wouldn't be able to afford. This way, they get accustomed/hooked on it and, thanks to the good pricing they got before, will be repeat, full paying customers after graduation. Besides, the discounts really aren't that huge anyway - new Macs are usually $100 off, software a bit more - but the point is that it keeps both parties happy.
If xaq wants to try Jaguar for less because it's the only way he will be able to use it, then I say go for it! There should be an option for his age group, just like I wanted the exact same option when I was his age. The sooner young'uns among us start using Apple products, the more experience they have when it comes time to use their computers seriously in the workplace.
It is obviously wrong for businesses to try to cheat Apple (or anyone for that matter), but for willing-to-pay-"underage"-students who are not considered "real" customers, long term effects will pay off for Apple, just as they do for college kids.
