Pre-Snow Leopard, I could use the following command: defaults write com.apple.loginwindow Finder /Applications/My-replacement-app-such-as-Terminal.app Which would a.) replace the Finder launching at login with an application of my choice, and b.) cause that application to launch instead of Finder when all other applications are quit. Is it possible to do this in Snow Leopard, or has this behavior been deprecated? (I don't want to disable Finder altogether, I just don't want it to start at login.)
