"Cut" and "paste" is a bad abstraction for moving a file. When you "cut" text and then don't "paste" it's the same as deleting the text. You don't want that for files (it would be too easy to accidentally delete the file). In fact, Windows doesn't work that way--if you fail to paste, the original file will remain in its original location.

Apple's abstraction is more honest to what is actually happening.
