Eh, I feel the opposite. Finder is much more usable to me, but of course I use the shortcuts like cmd-up to go up or down instinctively now. It is a bit ironic for such a mouse oriented OS everywhere else.

Still alt-clicking on the window title to see the whole folder hierarchy is easy to remember and doesn't clutter up the UI (err cmd-clicking? It's muscle memory so I forget). The fact that it works on most native apps with file titles as well I awesome.
