Reading through the post, it was clear that the author wasn't very familiar with Emacs. I'm a huge fan of the undo model of Emacs, especially with tools like undo-tree (although cycling through with M-y is basically as good for my use cases). The "replace the clipboard" bug doesn't exist because Emacs has a killring (I'm such a fan I bought killring.org years ago!), and the "text reflows" problem is completely solved use C-u C-space to traverse the mark-ring. His final point, that it is multiple operations, I simply disagree is a bug...multiple operations is fine, because I can compose them in a way that suits my workflow. Of course, in Emacs it would be trivial to write Ghost Cut (though it would only work within Emacs...).
