Mac OS X will not run on generic x86 hardware. It'll still be $129, and will require Apple-branded hardware. They aren't "dropping the mac" and going to a software-based business model, they're changing processors from the PPC series to the IA32/IA64 series.
Also, I believe it's against forum rules to discuss piracy of software. Go OSS if you want free. If you're going to get commercial software, then do the right thing and freaking pay for it. Don't break the law.
