oooh. You should never ship products developed with beta environments. Beta stuff is for larking around with, seeing what new features will be available and seeing if they have fixed the other bugs from previous version....Oh, and help them debug too
I personally wont develop customer software on anything unless it has been out in the field at least 6-12 months. Then there should be a few patches around to get rid of the show-stoppers. And don't forget, there is no such thing as support for Beta software. If you find a show-stopper, it won't get fixed until it is released, and that could be a couple of months.
