I downvoted you, and so I feel compelled to explain.

To your first point: On the desktop there are three ways to scroll: the scrollbar, the mousewheel, the trackpad. Of those three, only the scrollbar makes it obvious when you've reached the end of a document. Also, it's not all that different – Apple has brought the same bounce-back behavior to the desktop when scrolling with a trackpad.

To your second point: Some real world things bounce. Balls bounce, and rubber bands do in a sense too. Documents don't. They aren't emulating real-world behavior at all.

Whether the patents are good/valid is up to a whole other set of (apparently very arbitrary) rules. But the points you make to refute taligent's are very weak.
