My iMac can shutdown in 2 seconds, and be back online in 5 seconds. Of course I just use the SLEEP function! I don't get the fascination with the instant-on, wasn't that why "sleep" was invented? I use sleep mode, and reboot every few months. Now that's with my OS X based computers, my Windows computer I don't even bother with the sleep function. I have never found it very reliable. Maybe if you have the right hardware combo, but for me it's always been problematic.
Yea, Thats pretty much what I do with my Macbook. I just close the lid and it goes to sleep. when I come back and open it, it comes back up in a couple of seconds.
This never work right on my Windows laptop. Hybernate never works right either, even on a clean install. :crazy:
