Time machine is wonderful, but it makes a mobile Mac user cry- waiting for a backup to finish or cancel before we rush to a meeting makes life difficult. unDock adds a simple but critical piece of functionality to your Mac- an "Eject All" shortcut with super powers.

When you're ready to go, use either the keyboard shortcut (default: Control-Option-Command-Space) or the menu bar icon to unDock. All removable disks will instantly be ejected.

Feel the need to make unDock do more? You can supply your own AppleScripts that will be run when unDock is triggered.
