What the review is talking about is that when you click on All Programs, instead of getting an additional submenu, the tree of programs and submenu/folders appear as a scrolling list embedded in the left column of the Start menu. You can then click on submenu/folders to expand them in place like a treeview and can click a back button that appears at the bottom of the list to go back a step, or click on a program to run it.

So the answers would be No, No, Who Knows, and Yes.

But upon re-reading the blurb Drew included, I guess it should be "No" as well.
