Home Sweet Home
One really new concept in OS X is the Home folder. Each user has his or her own. What's there? A bunch of other folders, where savvy OS X-native applications, presumably, will automatically store your pictures, movies, sounds, and the like. To get to it, click on the Home icon in the Dock or the Home button in a Finder-window tool bar, or select Home from the Go menu. This should help novices who don't want to worry about what file goes where. Power users may be less enthusiastic, though, because Home folders keep popping up unbidden as the default places for storing documents. But you can't move or copy a file to a specific location by dragging it to a disk icon on the Dock, and then drilling down to the desired folder.
Dock Pop-Ups Hold your mouse button down on a folder or disk icon in the Dock and up pops a hierarchical menu that lets you navigate easily to any document or subfolder it contains. This feature is handy for opening documents.
