maybe they're talking about
Darwine ? Which is a project on getting windows applications running on mac and BSD.
My suggestion:
See if there's any way to dual boot Mac, if
yes, then,
step 1: Buy a computer from apple. Having mac on it.
step 2: Try to install windows on it.
step 3: DUAL BOOT!
step 4: USE BOTH!
not completely fool proof, remember, you NEED to find out if Windows can run with a PowerPC processor. And also ( IMPORTANT! ) if there's any way to dual boot a mac!
Edit: dual booting on macs WORKS! Atleast on intel macs, just check. Oh yeah, the other's already mentioned that. lol.
