I was surprised that I have another version of the 10.3 beta to try out again so soon.
I had quite a few issues with the beta early on, but they addressed them two releases ago. I'm not sure what they are correcting but it's rock stable for me right now.
EDIT Most of the issues I've seen people complain about, above, have been addressed - That being said, you'd all be complaining if they missed something in a hurry to rush this out

----------
At this point I think it is simply about sending a message. I am not sure if the developers at Apple are trying to send a message to Tim Cook, or if Tim Cook is trying to send a message to its users or to Wall Street, but it seems to me that someone within the organization is thumbing their nose at the idea of being subtle about the amount of testing that has gone into this update.
Sorry, but this comment made me laugh out loud. They are correcting issues - a few of them I had in a release two version ago, this isn't some kind of grand plot...
