1. I believe it is a violation of the Apple license terms to install the Mac OS on anything other than mac hardware.
2. A quality pc installation with the latest drivers and updates is at least as robust as a mac. There are a lot of happy PC-HW users out there, myself included.
3. Macs have some limitations, like the lack multiple touch screen drivers or the strange behaviour about memory paging.
If I were you, I'd go PC today. MAC OS on PC hardware seems to be a lose-lose to me.
