I agree, that the final release have poor memory handling problem, which I didn't see in pre release version without the last update.
I got low memory warning for the first time since I started to use v6i, and this is suppose to be the final? I hope they don't mean "dead" by calling it "final".
Over all feel is buggy and noticeably slow.  It's disappointing to say the least at this moment.
I'm also thinking of going back to pre release without the last update. It was far more stable than this final version.
