Fast Switching for Boot Camp (or not)
I must admit this definitely sounds interesting. Here’s how TUAW put it:
While this isn’t quite the built-in virtualization that some users were hoping for, it will minimize the startup, shutdown and boot times when switching between the two OSes. Detailed on Boot Camp’s new features page, Apple has hooked their safe sleep feature into Boot Camp to allow Mac OS X to save all your open applications and windows, and then boot over into Windows. Once you’re done in Windows, you can boot back over to Mac OS X and pick up where you left off - with all your open applications and documents put right back where you left them.
Great stuff Apple. Update: Maybe not, check this out.
