Love Data Driven Pages. This makes life so much easier.
What I think would make it even better is the ability to not only defihne a "Page Definition" for the whole layer, but to apply a Page Definition for the Labels.
For example you may wish to for all the parcels to be drawn, but label only the ones within you defined page. Currently to do this you need to add the layer a second time with the definition set on one for the labels and not the other to draw the polygons.
