Apple has caved in to public demand and released Boot Camp - software that will allow an iMac, MacBook Pro or Mac mini system to boot Windows XP. Of course, the Mac in question has to be Intel based, but it also involves a firmware upgrade and installing a package called Boot Camp Assistant into your Utilities folder. Nicely enough, the software does a non-destructive repartitioning of your boot drive, meaning that you don't need unpartitioned disk space beforehand. Very positive results have been reported so far.
