A number of people have talked about a better Finder. Tim Bray pointed me to a Finder replacement for OS X called Path Finder. Tim wasn't happy with the performance on a 500MHz machine. I'm happy to report that performance on a 1GHz machine is good and in just a few days I've become a convert. Overall, the user interface design is better and there are some features (like history) that just make a lot of sense in a file browser.
