Please, only those who have actually purchased a copy and have played with it enough to form a valid opinion (a few hours, perhaps). Rate how happy you are with it on a scale from 1-10, 1 being extremely unhappy and 10 being extremely happy. My rating - 8. Originally it was a 9, for me. No 10 because there are some very slight awkwardnesses (my iMac starts to go to sleep during front row - sort of, dock bounces acting a bit funny, photobooth moving backgrounds don't work that well, etc) - but I Guess that's to be expected. But I lowered it to an 8 after doing an upgrade on my iMac - it gave me the BSoL. Then I had to do an archive-and-install - it's working fine now. But for that annoyance (Cost me around an hour due to researching the problem), I am lowering my rating to an 8. What does everybody else think?
