I love the way my Mac smiles at me!
One of the coolest new features of Mac OS X 10.3 is secure delete. Secure delete removes the files in your trash, and then overwrites the location in the harddrive the information was stored. This makes it imposible to recover the files. This is great for security. I've used third part software to remove files with the Florida Air National guard. I think it's cool that this is built in to the OS.
Even better is this warning. I love the way the mac smiles at me, warning me what it's getting ready to do.
