I know you had said it was a rhetorical question but I do have to say something here....
Users aren't going to read the release notes they're going to want it to work. And if Jamie can complain about UI/Navigation points then I think it's OK if I can complain as well
If I was a serious beta tester (Dedicated time to filing bugs) then I would read the release notes, file bugs, subscribe to the newsgroups,etc...however I don't therefore simple complaining...doesen't hurt anything but maybe gives people a heads up on what
maybe to expect.
Filing bugs and such is the entire point of the Beta. If you aren't going to do that, then what's the point of you using Vista at this point? Read clause 7 of the licence agreement that you agreed to.
