It will happen, but as long as it requires tome technical jiggery-pokery from the user it will not be that prolific. What Apple does not want is a modified version of OS X that is readily available on peer-to-peer as all Hell would break loose.
this whole thing is ridiculous, it's like not being invited to a party and sneaking in through the basement. All the people at the party know you're not supposed to be there...
you can download music, steal programs, steal and boot any OS on any computer, but when is there going to be a point when people realize that just because you can do it doesn't mean it is ok.
Thinkpads are about the only Windows-centric kit that's on a par with Apple hardware. If could run MacOS X on a Thinkpad legitimately, I'd be prepared to make the investment, especially if this would allow me to dual boot when I need to.
I've been using a succession of Thinkpads as company machines for the last decade, and I have to say, I'm a big fan - almost to an inverse proportion to the extent I hate Windows. Slick, cool, matt black, with manly corners. My T42 is a seriously nice piece of kit - I often lament the fact that I have to ruin all that great work by running a POS operating system on it. I think Thinkpads and MacOS would pretty much be a perfect union for me. People talk about 'killer apps' - just the fact that I could buy a MacOS lappie with a built-in right mouse button would be compelling enough for me. If I could make it a Thinkpad, that'd seal the deal.
