I think the way I'd put it is that most of the claims there are orthogonal to the UI complaints people make. I don't see people complain about the ease of browsing to a desired place, sometimes I do it with the toolbar, sometimes the URL bar, sometimes the start page, who cares? None of these things have anything to do with borders on buttons... If something has a clear advantage people don't tend to complain about it. The ability to search from the URL bar has a utility that is clear. Making tabs break a paradigm and be (mildly) harder to see doesn't really seem to have any utility and the system would work the same both ways. I still use Firefox, don't get me wrong. But I don't understand why this stuff is changing before being made into a skin so that us old people can have something stay the same for a few weeks.
