I've had good luck installing the public release the day it's released and haven't had any problems before, so I will probably do the same again this time.
Given I'm already running the PB on my iMac I'll be updating that straight away. Will see how things go for a week or so on that before updating my MBAs, because at the minute there are still too many things not working.
No because that is what I am running now and am very happy with it other then the weird as all heck storage issue with it showing your HDD way fuller then what it can hold! LOL
