Bootcamp
Wow, a hundred times wow! Apple just released an early version of Bootcamp (cool name!), which allows Intel based Mac's to boot into Windows XP.
It seems as though it's a dual-boot loader so you'll need to restart to get into the other OS, in contrast to some rumours about running them concurrently.
This is going to be huge.
