Tony, things have changed since the old days. I agree, it used to be you'd wait until the .10 or so version came out before you'd use it, but with the beta testing they knock out 75% of the bugs before they release. I agree, you should never use a .0 version for a live store, but the .1 is usually passable, and .2 is pretty good.
Should they have beta tested one more round? Probably, but I can understand this method too - they get a WHOLE LOT more testers this way
With all the new features and completely redesigned back-end, it is actually in pretty good shape for a .0 version.
