nice, but the question is, what can i do more with OS X that I can't do already with Windows and Linux?
Try it and see. At least this way you'll be able to see if there is anything or if the OS works for you personally
When the intel OS X first came out I spent 3 days trying to set it up on a Dell machine I had. What a joy when I got it running. I subsequently bought a MacBook Pro and it has been a great machine - I run Windows and Linux on it also via Parallels. OS X is a lovely oS (coming from a Windows background) and I'd suggest playing with it - you might be pleasantly surprised
It's doubtful that the OS X experience on a "hackintosh" will be as pleasant as it is on a mac. Mac OS X is designed to work really well on a small selection of hardware. There will probably be driver issues, and all kinds of other problems, on commodity PC hardware. Nevertheless, who knows, you might get lucky, have very few issues, and maybe even fall in love with "the world's most advanced operating system."
I think the whole point of the "Hackintosh" concept is that it's a custom PC with similar hardware to what Apple uses. If you take the time, it's not that hard to find out which device chipsets OSX supports, and most chipsets are used by a variety of manufacturers. Not to say that everything will be flawless, but most major issues can be avoided by carefully choosing the hardware.
