Time Machine

Couldn't help noticing the Leopard preview on Apple's web site (it's currently Apple's yearly World Wide Developer's Conference/Orgy), specifically the Time Machine feature.

Once again I'm struck by the UI. Undelete is nothing new, and frankly it shouldn't be that hard to implement. But Apple really focuses on the UI for such utilities, and that's what makes people love their Apples. This feature's in Windows would be coded by some incompetent intern and end up being some inscrutable dialog box.
