A couple more I just thought of while I was outside:

If you have a blank hard drive (or whatever), you can hold a key combination during power-on, to enter a recovery mode where EFI will download a recovery mode installer over the internet, so you can format your hard drive, reinstall OSX, or recover from time machine, all without any recovery media or anything.  All over the internet.

You can install OSX onto an external hard drive.  Great when you need to do something in a test environment.  To boot from it, just hold Option during power-on, and it will present you with a list of attached bootable media, so you can choose the external disk as your boot disk.

Tools such as shirtpocket.com Super Duper will allow you to clone your internal hard drive to an external hard drive, and make it bootable.  If you pay the nominal $30 then you can even schedule automatic incrementals from the internal to external, so if your internal HD gets hosed, you can simply boot from your external as if nothing ever went wrong.  This is useful as a backup *augmentation* in addition to time machine.
