I shut it down before I go to sleep and turn it on when I get home.Not cool if sleep doesn't work -- shutting down every time you walk away from the computer is no good, and keeping it powered 24/7 is no good either.
I will test sleep later. I think it works...
Edit: Updated to 10.8.1. Nothing broke! Everything is fine except Chimera (Still can't boot from it)
As for sleep, doesn't work. Oh well! Only time I see a use for sleep is when closing a laptop.
