I've noticed that WinXP can shutdown in 25% of the time it takes Parallels to hibernate, and it boots up in about 6 seconds or so compared to the minute it takes to load the hibernation image. For most times I wish to hibernate when I am working on things, but when I am shutting down my MBP or just want to quit Parallels, it'd be awfully nice if it could just shut down WinXP for me automatically.
