I ain't using it until software like Daemon Tools and a lot more of similar progs (drivers etc.) are supported. There are a lot of companies that say: "Hey it's beta and we won't support it until it's final!". So, I'm sticking with the "final" OS-es right now. I'm sure it will be one of the best there is (unless microsoft decides it doesn't and overloads it with crap and junk just like Vista). :D
