Seems the development Intel/Mac systems from Apple are starting to make the rounds. The folks at Think Secret have some initial details on the hardware. The only problem they seem to have run into with running Windows XP on it was with the video card. Running Intel/OS X on a non-Apple/Intel system didn’t work though.
The ability to dual boot an Apple system between Mac OS X & Window XP might be an attractive option. Perhaps a three hard drive solution would work best: 1 for OS X (Mac OS Extended file system), 1 for Windows XP (NTFS) and 1 for shared data between the two (FAT32 file system). I wonder if a shared iTunes directory on the shared data drive would work with iTunes on both Windows XP and OS X?
