On Windows XP, you can hibernate your system (dumps RAM to the hard drive and powers down... you boot up much quicker, and pick up right where you left off). I use hibernate all the time on my PC. What news of hibernate and compatibility with Dual-boot Intel Macs? Also, does OS X allow hibernating? It seems like this would be a great way to switch from one OS from the other, faster than a complete reboot, though of course not as nice as Parallels' solution. Has anyone tried this?
