I loved the "brushed metal" look in 10.3, I remember trying to install various mods to force "brushed metal" onto more applications. You can't really tell from the static screenshots, but Apple put a lot of effort into making brushed metal windows look good -- it wasn't just a static texture, but instead a composition of multiple layered elements that scaled in different ways as you resized the window. I remember seeing "brushed metal" themes on Linux and Windows at the time, and none of them could come close to 10.3's level of polish.
