I really liked the Mac "forked" file system. File types and bundles were simple and worked really well. They also facilitated "drag and drop" application installs, where the Finder did most of the work keeping track of where applications lived. The app install process on Windows makes me weep (I think that Visual Studio installs well over 10,000 keys in the registry. What the hell? This number should be zero in a well designed system . . . but don't get me started on the disaster that is COM). Incidentally, Windows NT has file forks. They're not often used, and lots of utilities don't know about them, but they can be quite useful.
