Apple likes showing off. In Leopard lots of things are improved, the UI is more consistent and polished. Yet there are a number of completely ridiculous aspects of it that go quite a long way towards demolishing Apple's reputation as a leader in UI design. Take for example the new Dock, which besides completely pointless is also an ergonomic nightmare, heavy on resources and ugly. Did I mention pointless? (Thanks to the_unknown_Apple_dev for the no-glass option!).
The linked blog entry more or less sums up most of the things I found completely, utterly stupid while looking at Leopard images and videos online. I've got some more, such as the relatively dark gray 'platinum' look (I prefer the lighter gray of the 'inactive' windows), CoverFlow (mostly useless in the Finder if you ask me), the proliferation of etched text among others.

Update: As usual, a really good and thorough review of Leopard by John Siracusa, can be
found at ArsTechnica.
