It is never a good idea to install a brand new release on a production system unless you have to (i.e. if it is the only easy way to fix a show-stopping usability/security/compatibility issue) - this goes for any software. Play safe and let the pioneers get scalped, and/or try it out on a less critical machine first.
I recently bought a new netbook and rather than waiting a couple of days or installing the beta to upgrade later I put an older release on. 10.04 in fact, rather than 10.10, as that is an LTS release and I was in a cautious mood.
