I find in OS X it can be a real pain sometimes if you have a very long list and you want to move something to a spot several pages away in the list. Instead of moving everything by selecting it and dragging it the whole way, just select what you want to move. Then scroll to the spot in the list where you want the items moved. Command-click an item at that spot to make a discontiguous selection, and then move that item just enough that the insertion line shows up.
When you let go of the mouse, all the items you selected will move to the target spot. Depending on how you did it, you may have to put the one item you selected second back to its spot, but I find this is still far less work than dragging the moved items manually would be.
[Editor's note: In all my years of Mac usage, I had never heard of this method of rearranging a long list of items through a non-contiguous selection - quite useful!]
