Apple is now supporting Windows XP on their Intel-based Macs! No more hacked bootloaders required. Apple just released its beta of "Boot Camp", which will provide not only the bootloader, but a driver set as well. All you've got to do is provide your copy of Windows XP SP2.
I don't have an Intel-based Mac, but this is a huge step in the acceptance of a great OS, with support for some of those applications that are only available on the Windows platform. Now if only we could get better virtualization or emulation (like WINE), inside of OS X! Dual boots are nice, but switching back and forth requires an investment in time to reboot, especially if all you want to do is use Outlook!
