Mine are there, they just aren't pinned. In vista they were in a seperate window pane so they would be up at the upper left at all times, even if you scrolled down through your other folders. So now if I want to organize things, I dig down through my folders, then I have to scroll the pane all the way back to the top to get to my favorite folder to drag a file into it. Then scroll all the way down and continue on with other folders
In vista they were "pinned" up and were visible at all times, so you could at any time drag a file into a favorite folder and keep on going without having to scroll around everywhere.
