Setting aside the legality issue for a moment, it just isn't worth installing (or trying to install) OS X on 99% of the PC notebooks out there. The compatibility issues are so widespread that you're pretty much guaranteed to have at least two or three major functions missing in a given computer unless you plan ahead and read reviews of people who've tried it with a particular machine. And even then, on "compatible" machines, you often have to download various patches, use external components for setup (ethernet cards, keyboards, monitors), if not for daily use, and in general, deal with an unreliable combination of software and hardware. I'm a long time Windows user and fond of tweaking my gear, but as someone who has tried OSx86 myself, I'll wholeheartedly say it isn't worth the time or trouble. Instead of buying a PC and hoping to install OS X on it, save the money for a refurbished/used/new Macbook/Mini/iMac/etc. If that's too expensive, try a G3 or G4 iBook; I scored one for $200 on Craigslist, and a few weeks of using it showed me I could get the hang of the OS full time. Either option will be infinitely more satisfying (and productive) than wasting endless hours trying to figure out why your sound/wireless/ethernet/card reader/etc isn't working on your Hackintosh.
