I knew some folks would hack it, there have been Mac-on-PC hacks around for quite a while. Having things run on the same architecture just makes it a LOT easier.
Of course, even if they licensed OS X, I'd probably buy Apple hardware anyway. It's as well-designed as the OS is, and why would you want to buy the best software and run it on mediocre hardware? (ie a $300 machine.) I like my wicked-cool Aluminum laptop with backlit keyboard. I just wish I'd had a chance to play with all the cool features by now. Sooner or later...
