Take out the trash
As green as Apple may be, don't expect to find a "Recycling Bin." Let's be honest, what you put in there was really trash, and Apple agrees. The Trash application also doubles as an eject function for any USB drives that you may have plugged in. When dragging a USB drive to the Trash icon, it morphs into an Eject icon and then you can safely turn off and remove the device.
