If you have LS120, Jaz, Zip, Orb, or other removeable storage media, you can drag the icon for the mounted device to the Trash. Boom! Instant eject Mac style!
[Editor’s note: This option in no way interferes with the normal methods of unmounting volumes (right-click and choose Unmount from the context menu, use the Unmount menu in DriveSetup, or use the unmount and eject commands from the shell). If you feel that this option just perpetuates UI mistakes from the MacOS world, then don’t use it! It’s there as a convenience, to help users migrating from other platforms feel more at home.]
