Claimed4All - not sure if your post was in response to the original or my post; But a few more thoughts ...
First off, if you have the GM release through proper channels, you are a certified member of the Mac Developer program. Anyone that has Lion and is not a member of the program has gotten their hands on software they shouldn't have.
Secondly, everyone that has any appreciable amount of beta testing or early release testing for Apple or Microsoft realizes that when they download one of these they are getting buggy software. ALL software is buggy, even OS X 10.6.8 still has bugs in it.
As someone that has played with the previous non GM versions of Lion, I can attest to the difference in the quality of the GM build as compared to earlier versions. There is a very high probability that this build (11A511) is the one that is released later this week. If they release this version, no one on this forum would claim to say that it is a "bug-free" release; In fact if you look back at the history of OS X major number releases, the majority of bugs from the 10.x releases are addressed in the first 2 10.x.# releases. Each of these releases are typically released within the 60-75 days of the GM being released. That is when Lion's long-term stability and reliability will be cemented. But with that said, all software goes through this type of lifecycle. For those that haven't done QA on a MASSIVELY large project before, it is a REALLY HARD THING TO DO. It doesn't come out of the "womb" perfect.
