Selling OS X directly to other peecee makers would be a bad thing, Apple overprices it's products and it'd cut it's legs out. There will be I'm sure a few posts on this board by loud, delusional, idiots (living in the parents basement no doubt, out of touch or step with reality) who will shrilly say, with glee even, "see SEE, now everyone will be hacking OS X to run on peecees... " and when they open their pie holes, simply nod, think about how they're the minority, not stable, and haven't lives.
The reality is there will be (thankfully) no LEGAL way to run OS X on a peecee (for now). Sure there will be a few hardworking luser geeks with too much time on their hands cracking the latest version to get it to run on some machines, and probably not well. And they'll share these cracks with the luser "warez" crowd and some lusers probably on this board even will get their hands on it. Then the next OS X update will make that null and void but people will go on with the current hack. And mind you they may make it so certain apps wouldn't work well on a peecee motherboard too so it's really for idiots to say "look LOOK OS X on my peecee.... (mother yells) are you ever going to move out of that basement, you're 36!!!"
So while there will be people here saying how they're going out and buying or building some piece of crap peecee and are going to run out and steal OS X right now (because losers that do this never legally buy software, they lack morals or a conscience) this is how they work. And they will get a cracked version of OS X working for awhile....
... but ignore them, because they should be ignored.
To get a cracked version of OS X and run it will take a lot of effort, 99.9999 percent of most average computer users with peecees (aside from having no taste) don't have the wherewithal, time, effort, or in many cases the savvy to actually put a cracked version on the Intel machine, it won't be easy or supported and the masses en mass won't even know there's a way, and that'd fine.
So it's not the next coming, OS X will mostly be exclusive only the Macs (thankfully) and hopefully if we can get Windoze working on a Mac then those who have to look at the craptacular, ugly, clunky, buggy, weak weak OS known as XPee on the Mac, more power too them. Heck, I'd love to play HalfLife 2 but am not getting a P.O.S. XSux or peecee just for it, it's compelling though if there was a way to play it on the Mac.
This may be a great year! (As an Apple stockholder it already IS!)
